The endocrine system includes glands that secrete hormones directly into the bloodstream to regulate distant target tissues and organs. The main endocrine glands are the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries and testes. The hypothalamus and pituitary gland act as a master regulatory unit, controlling most other endocrine glands through negative feedback loops. Hormones carry out functions like growth, metabolism, sexual development, and fluid balance through binding to receptors on target cells.
Csf formation, absorption and circulationDr Sara Sadiq
The cerebrospinal fluid is produced by the choroid plexus in the brain ventricles at a rate of around 500ml per day in adults. It circulates through the ventricles and subarachnoid space around the brain and spinal cord, where it acts as a cushion and aids in waste removal. The composition of CSF differs slightly from blood serum, with varying concentrations of proteins, glucose, and electrolytes. Increased intracranial pressure can result from conditions that enlarge the brain or increase CSF volume such as tumors, edema, infections, or obstructions in CSF flow and reabsorption. Lumbar puncture allows analysis of CSF for diagnostic and therapeutic purposes.
1) Human development begins with the fertilization of an egg (oocyte) by sperm, forming a single-celled zygote. Through processes such as cell division, differentiation, growth and rearrangement over 9 months, the zygote develops into a baby.
2) Development is divided into prenatal (before birth) and postnatal (after birth) periods, with major developmental changes occurring during embryonic, fetal, infant and childhood stages.
3) Both male and female gametes are produced through meiosis within the ovaries and testes, respectively, reducing the chromosome count so that fertilization restores the normal diploid number.
The document describes the respiratory system and its functions. It discusses how respiration includes pulmonary ventilation where air moves in and out of the lungs, gas exchange between the blood and air in the alveoli, and transport of gases between the lungs and body cells. It also describes cellular respiration where oxygen is used by cells and carbon dioxide is produced. The respiratory organs include the conducting zone which carries air to the respiratory zone in the lungs where gas exchange occurs.
Fertilization occurs when a sperm meets and fertilizes an egg in the fallopian tubes. The fertilized egg then undergoes cell division and implants in the uterus. It develops into an embryo supported by the placenta and amniotic sac. The placenta functions to exchange gases, nutrients, and waste between the mother and developing fetus. It is connected to the fetus by the umbilical cord, which carries oxygenated blood to the fetus and deoxygenated blood away.
The pineal gland, also known as the epiphysis cerebri or pineal body, is a small endocrine gland located in the brain. It produces the hormone melatonin and is involved in regulating sleep cycles and seasonal functions. The pineal gland sits above the midbrain and between the thalamus. It receives blood supply from the posterior choroidal arteries and drains into the internal cerebral vein and great cerebral vein of Galen.
This document provides information about the female reproductive anatomy and system. It describes the external genitalia including the vulva, labia majora, labia minora, clitoris, and perineum. It then discusses the internal genitalia such as the vagina, cervix, uterus, fallopian tubes, and ovaries. It explains menstruation and the development and release of eggs through the process of oogenesis.

1) The lungs develop from the foregut endoderm and associated mesoderm. The endoderm forms the epithelial lining of the trachea, bronchi, and alveoli while the mesoderm forms the cartilage, muscle, and connective tissue.
2) During the 4th week, lung buds form as outgrowths of the foregut endoderm. Tracheo-esophageal ridges then fuse to separate the trachea from the esophagus. Incomplete fusion can lead to tracheo-esophageal fistulas or esophageal atresia.
3) Over successive developmental stages, the lungs continue to branch and the pleural membranes form, separating the pleural
The document summarizes mechanisms that regulate extracellular fluid osmolarity and sodium concentration. Two primary systems are involved - the osmoreceptor-ADH system and thirst mechanism. When osmolarity increases due to water deficit, osmoreceptor cells signal the pituitary to release ADH, which increases water reabsorption in the kidneys to dilute extracellular fluids. Thirst also increases to promote water intake when osmolarity rises. Together these feedback systems precisely control extracellular fluid volume and composition.
The document provides an overview of human sexual and reproductive anatomy and physiology. It describes the key functions and roles of both the male and female reproductive systems. The male's role is to produce sperm and deliver it to the female tract, while the female produces eggs and provides a nurturing environment for fertilization and development. Both sexes produce hormones that influence sexual development and function. The document then goes into extensive detail about the internal and external anatomy of both male and female reproductive organs.
The respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, bronchioles and lungs. It allows for the intake of oxygen and removal of carbon dioxide through breathing. The nose and pharynx warm and humidify air before it reaches the lungs. In the lungs, oxygen diffuses into the blood in alveoli and carbon dioxide diffuses out. Breathing is driven by the contraction of the diaphragm and intercostal muscles which expand the chest cavity.
This document discusses oxygen and carbon dioxide transport in the blood. It explains that oxygen diffuses from alveoli into pulmonary blood and is carried by hemoglobin in red blood cells. Carbon dioxide diffuses in the opposite direction and is transported in the blood plasma and bound to hemoglobin. The document outlines factors like pH, temperature, and 2,3-BPG concentration that affect the oxygen-hemoglobin dissociation curve and the affinity of hemoglobin for oxygen. It also describes the Bohr effect, chloride shift, and Haldane effect which influence oxygen and carbon dioxide transport in the blood and tissues.
The menstrual cycle is normally around 28 days and has 4 phases - follicular, ovulation, luteal, and menstruation. It is regulated by the hypothalamus, pituitary gland, and ovaries. Key events include follicle development and selection during the follicular phase, ovulation triggered by the LH surge around day 14, corpus luteum formation and progesterone secretion in the luteal phase, and menstruation if implantation does not occur. The endometrium thickens and is shed each cycle in response to rising and falling estrogen and progesterone levels.
The female reproductive system produces a finite number of eggs during fetal development. During puberty, hormones cause follicles in the ovaries to mature and release eggs, with only a small number reaching maturity. If an egg is fertilized, it develops in the uterus, whose lining changes each month in preparation. If not fertilized, the corpus luteum degrades and menstruation occurs.
The menstrual cycle occurs approximately every 28 days in human females from puberty to menopause. It involves several phases: the menstrual phase where the uterine lining is shed; the proliferative phase where the ovaries develop follicles and estrogen levels rise; ovulation on day 14 where an egg is released; and the luteal or secretory phase where progesterone levels rise to prepare the uterus for potential pregnancy if fertilization occurs. The cycle is regulated by hormones from the hypothalamus, pituitary gland, and ovaries. Proper understanding of the cycle allows couples to plan intercourse for maximizing chances of fertilization and pregnancy.
The menstrual cycle can be divided into four phases: the menstrual phase (days 1-5), the follicular phase (days 1-13), the ovulation phase (day 14), and the luteal phase (days 15-28). During the follicular phase, an egg cell matures and estrogen levels rise. On day 14, the pituitary gland triggers ovulation, releasing the mature egg. If the egg is not fertilized during the luteal phase, menstruation begins again, starting a new cycle.
The fetus grows rapidly in the third trimester, reaching weights of 3 pounds at 2 months before birth and 7 pounds at birth. While the major organ systems begin developing early in pregnancy, the nervous system, kidneys, and liver are not fully mature at birth. After birth, the newborn must adjust to breathing air and circulating blood independently of the mother. Important adjustments include opening the lungs and initiating breathing, closing the foramen ovale and ductus arteriosus, and ramping up cardiac output and blood pressure to support the systemic circulation. Premature infants face additional challenges with immature respiratory, digestive, and immune systems.
This document provides an overview of respiratory physiology, covering the definition and function of respiration, the steps of respiration, the structure and function of the conducting and respiratory zones of the lungs, lung volumes and capacities, mechanics of breathing, gas exchange, transport of oxygen and carbon dioxide in the blood and tissues, and control of breathing. Key points include that respiration involves the exchange of oxygen and carbon dioxide between the environment and body cells, occurring in five steps including ventilation, diffusion, transport, and cellular respiration. Gas exchange takes place in the alveoli via differences in partial pressures and is facilitated by a large surface area and thin diffusion barrier. Oxygen is transported in both dissolved and hemoglobin-bound forms in the blood, while carbon
The document provides information on the functional anatomy and physiology of the respiratory system. It discusses the importance of understanding respiratory anatomy and physiology in fields like pulmonology, anesthesiology and critical care. It then describes the processes of external and internal respiration, the structural and functional unit of alveoli, and the roles and functions of various respiratory structures like the nose, pharynx, larynx, trachea, bronchi, lungs and pleura. It also discusses topics like mucociliary clearance, Kartagener's syndrome, airway innervation, Weibel's model of the tracheobronchial tree and blood supply to the lungs.
The document provides an overview of the human nervous system, including:
- The central nervous system (CNS) which includes the brain and spinal cord. The brain is made up of the cerebrum, cerebellum, diencephalon, medulla oblongata, pons, and spinal cord.
- The peripheral nervous system (PNS) which includes nerves and ganglia that connect the CNS to the rest of the body. It has somatic and autonomic divisions.
- Neurons, the basic functional units that transmit nerve impulses, and neuroglia, supporting cells that nourish neurons. Impulses are transmitted via changes in electrical potentials across neuronal membranes
There are four valves in the heart that prevent backflow of blood and ensure it flows in one direction. The atrioventricular valves are the tricuspid and bicuspid (mitral) valves between the atria and ventricles. The semilunar valves are the pulmonary and aortic valves between the ventricles and arteries. Each valve has distinct features like the number of cusps and location that allow blood to flow properly through the heart.
The document summarizes key stages in human embryonic development from fertilization through the first few weeks. It describes the progression from a fertilized egg to a blastocyst, implantation, formation of the three germ layers and early development of organ systems. It also reviews embryonic tissue development and the process of ossification.
Pulmonary ventilation functions to maintain favorable concentrations of oxygen and carbon dioxide in the alveoli during rest and exercise. Inspiration occurs when intrapulmonary pressure is reduced below atmospheric pressure through contraction of inspiratory muscles, while expiration is usually a passive process at rest but involves expiratory muscles during exercise. Pulmonary ventilation, measured as minute ventilation, ensures complete gas exchange before blood leaves the lungs for transport throughout the body.
The document summarizes the anatomy of the lungs and related structures. It describes:
- The lungs have two lobes separated by an oblique fissure. The left lung is smaller due to the heart protruding further left.
- Structures pass through the hilum, including the pulmonary artery, veins, and bronchi. The right lung has three lobes separated by fissures.
- The lungs are surrounded by pleura and indented by the heart and ribs. Segments are the functional units of the lungs supplied by their own bronchus, artery and vein.
Fertilization occurs when a sperm enters an ovum and their nuclei fuse to form a zygote with 46 chromosomes. This takes place in the fallopian tubes. The zygote then undergoes cell division, forming a morula, blastula, and gastrula. During the gastrula stage, the three germ layers form - ectoderm, mesoderm, and endoderm - which will give rise to the embryo's organs and tissues. The blastocyst then implants in the uterus, where the placenta develops to support fetal development over the following months.
The document provides an overview of the human reproductive system, including definitions and key parts. It describes both male and female external and internal reproductive organs. The male system produces sperm and the female system supports pregnancy and childbirth. The reproductive cycle in females includes menstruation, ovulation, and changes regulated by hormones. Fertilization can lead to pregnancy, in which a placenta develops to support fetal growth until birth, after which lactation provides nutrition for an infant.
The document discusses the history of anti-police protests in New York City and current groups involved in advocating for police reform. It notes that New York has a long history of police injustice dating back to the 1943 Harlem Riots and 1964 Harlem Riot. More recent protests have been led by groups like the National Action Network in the 1990s and in response to George Floyd's killing in 2020. Current groups advocating for issues like defunding the police, allocating funds to community programs instead of policing, and holding police accountable include VOCAL-NY, Correct Crisis Today NYC, Communities United for Police Reform, and Million Hoodies. The document analyzes the tactics and opposition faced by these groups and notes

Police Misconduct And Brutality Of Police OfficersLeslie Lee
This document discusses police misconduct and corruption. It begins by defining police corruption as when an officer uses their position to obtain improper financial benefits. It then discusses different forms of police abuse, including physical abuse through excessive force, psychological abuse through harassment and intimidation, and legal abuse through unlawful searches and seizures. The document also mentions that selective enforcement, such as not arresting an off-duty officer for drunk driving, can be a form of misconduct. Overall, the document provides an overview of the various types and definitions of police misconduct and corruption.
The article argues that police cannot be reformed through liberal reforms like increased oversight and accountability. The author argues that the only way to reduce police violence is to reduce contact between the public and the police by cutting police budgets and the number of officers. The author advocates for abolishing the police and redirecting funds to social services to reduce the need for police in the first place. The article discusses how policing in the US emerged from slave patrols and helping the rich suppress labor movements. Reforms in the past like increased oversight and diversity hiring have failed to curb police violence.
This document summarizes an essay about police brutality. The key points are:
1) Police brutality remains a serious human rights issue in the US due to barriers to holding officers accountable for excessive use of force.
2) Investigations find police brutality persists across all cities, but systems meant to deter abuse instead guarantee officers impunity.
3) While some data on police brutality exists, it is not used effectively by administrators or prosecutors to deter future incidents.
4) Most cities now recognize reforms needed for troubled police departments, but officials are unwilling to seriously discipline officers until high-profile cases are exposed.
This document discusses the 1992 Los Angeles riots that occurred after the Rodney King verdict. It provides background on the tensions between citizens and police in LA leading up to the riots. On the day of the verdict, when the four police officers were found not guilty on most charges, widespread unrest and violence broke out. The riots initially started at the intersection of Florence and Normandie when a crowd formed in response to a police arrest. When the overwhelmed police retreated, it empowered the mob and the riots spread quickly across LA over the next few days.

-Now there are more mandatory arrest being made.
7 Basic Requirements for an Act to be a Crime
Defense must prove failure of a basic requirement
• 1. The act requirement – mind & Body
• Conscious act not an unconscious act or reaction
• Not a status or condition
• 2. The legality requirement – prohibited by law
• Thoughts without action – no crime
• Choosing to not fill out sex registration forms – is a crime
• Good Samaritan?
• 3. The harm requirement
• 4. The causation requirement

• 5. The mens rea requirement (guilty mind)
• 6. The concurrence requirement
• Must be a criminal act with criminal intent (Ex: striker – rock –window)
• Exceptions – felony murder
• 7. The punishment requirement – its must already exist

Criminal defense negates basic ingredients of
crime.
• Crime – must be known to the police
• Not all crimes reported are cleared
• DA will not always prosecute
• Defense negation of crime elements examples:
• Insanity defense; legality requirement lacking; duress, self-defense.
• State tries cases on behalf of the state
• Victims can file civil law suits for pain and suffering
Typologies of Crime
• The French created the following three categories accepted
worldwide
• Felonies - severe
• Misdemeanors – minor
• Violation - fines
• As Criminologist we will also focus on the following
• Violent crime
• Crimes against property
• White collar and corporate crime
• Drug, alcohol and sex-related crime

Reasons for Measuring Crime
• Researchers collect and analyze data to test theories about why
people commit crime.
• Researchers and criminal justice agencies need to enhance their
knowledge of the characteristics of various types of offenses.
• Criminal justice agencies depend on certain information to facilitate
daily operations and anticipate future needs.
The Research Process
• Topic – research question
• Theory: is a set of principles that explain how 2 or more phenomena
are related
• May choose to use a hypothesis or not.
• Methodology (qualitative vs. quantitative)
• Will you use secondary data or primary data
• Analysis
• What did you do, findings, discussions and conclusions

Chapter Two: Defining Crimes and
Measuring Criminal Behavior
-Slides and data in this outline are from Adler, Mueller, and Laufer (2007, 2013,
2018 & 2022); Siegel (2015); and modified by Manning (2007, 2013, 2015, 2018
& 2022).
Scared Straight Program – 1978 Rahway Max Prison
-Politically motivated –fit the get tough on crime bill
-Three year post experiment study shows evidence must be evidence based
-Criminologists embrace a systematic empirical study of the nature and extent of crime.
Example of successful criminology research based policy:
-Domestic violence research between 1981-82 shows police counseling and temporary separation was
not effective.
-Now there are more mandatory arrest being made.

• Thoughts without action – no crime
• Choosing to not fill out sex registration forms – is a crime
• Good Samaritan?
• 3. The harm requirement
• 4. The causation requirement
• Behavior in question caused the harm – not a 3rd party

Racial profiling has been studied extensively in New York City, where researchers have found evidence that it does occur. Studies have shown that police activity disproportionately targets minority groups, which some attribute to the "Broken Windows Theory" of policing minor crimes. However, the facts also show that police focus extends beyond just disorderly individuals in certain areas. A police chief's email condoning racial profiling has raised concerns and could lead to his firing if found to be legitimate. Debate continues over racial discrimination and unequal treatment in law enforcement.
Official crime statistics collected by the Home Office provide information on crimes known to the police, but have limitations as not all crimes are reported. Only around 30-50% of crimes are actually reported to and recorded by the police. Victimization surveys aim to uncover a truer picture of criminal activity by asking people directly about crimes they have experienced. However, they also have limitations as they rely on victim memory and definitions of crime. There are many factors that influence the reporting and recording of crime and how accurately statistics represent the real level of criminal activity.
1. Police misconduct against people of color has been an issue for centuries and continues today, manifesting as racial profiling, excessive use of force, and discrimination.
2. High-profile cases like the shooting of Oscar Grant show how police often assume people of color are criminals and use force without justification. Excuses like fearing for safety are commonly used to explain away brutality against minorities.
3. Statistics indicate most police departments have internal problems like overlooking rule violations and abuse, revealing a systemic issue with police accountability that has led to distrust between communities and law enforcement. Reform is needed to curb misconduct and restore trust.
The document discusses public perceptions of the police, noting that views vary widely due to personal experiences with law enforcement and factors like socioeconomic status. While many see police as protecting communities, others perceive excessive force, racial profiling, and brutality as undermining trust in the police. The document argues that without law enforcement, there would be increased crime like murder, robbery, and assault.
This document provides an overview of crime and violence. It begins by defining crime and describing different types of crimes and criminals. It then discusses the four main categories of violence: homicides, assault, rape, and domestic violence. The document outlines different types of crimes such as violent personal crimes, occasional property crimes, occupational/white-collar crimes, corporate crimes, public-order crimes, organized crime, consensual crime, and hate crimes. It also discusses biological explanations of crime and how factors like gender and age relate to crime rates. Finally, it covers approaches to controlling crime through rehabilitation, prevention, and social policy reforms.

On the Substance-Related Treatment Gap in Medicare-Only CoverageElspeth Slayter
This presentation details a policy analysis related to the gap in health insurance coverage for adults with Medicare-only coverage who have substance-related disorders in need of treatment. Adults with Medicare-only coverage are rarely addressed as compared to elders or people who are dually-eligible for Medicaid and Medicare. And further, people don't like to think about substance-related disorders…I propose a state-specific plan to address coverage for such conditions for a potentially needy population in a way that promotes long-term cost-savings.
This document provides an overview of Medicaid claims data and how it can be used for program evaluation and research. It describes the key components of Medicaid claims data including eligibility data, diagnostic codes, procedure codes, and expenditures. It outlines some of the strengths of claims data for population monitoring, benchmarking, and expenditure analysis, as well as limitations related to clinical validity and completeness. Accessing Medicaid claims data requires working with state Medicaid agencies or research groups that have obtained the data.

Slayter Untangling Adoption Disparities For Children With DisabilitiesElspeth Slayter
This document summarizes a study examining disparities in adoption outcomes for Black children with disabilities from the foster care system. The study found that compared to non-Black children with disabilities, Black children tended to be older when adopted and more likely to be diagnosed as emotionally disturbed. Black children also experienced longer waits between termination of parental rights and adoption, and were more likely to be adopted by single parents or non-relative families. However, Black children were more likely to receive post-adoption subsidies. The study aims to better understand these disparities and their causes.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

29. No recognition of disability
• Intersection with
disability
• Ruderman Family
Foundation report on
disability & police
violence
• 30-50% of people killed

30. Measuring police brutality
• Measurement a challenge due to
underreporting (ACLU, 2020)
• Citizen complaint rates often reflect
underreporting
• Historically:
– Low SES most at risk
– 13.6% citizen encounters resulted in
complaints of abuse (Police Services Study,
1982)
31. Measuring police brutality
• Recommendations from ACLU are to
focus on:
– Police shootings/firearms discharge
– Use of physical force
– Understanding official policies
– Counting lawsuits
35. Causes of police brutality
• 2 competing theories re: lethal force in
literature
• Threat hypothesis: Explained by racism &
influence on interpersonal interaction (Jacobs &
Obrien,1998)
• Community violence hypothesis: Direct
response to higher rates of violent crime in
Black communities (Smith, 2004)
36. Causes of police brutality
• Traditional arguments focus on implicit
bias & “a few bad apples” (Mock, 2018)
• Newer research identifies structural racism
at state policy level (Mesic, Franklin, Cansever, Sharma,
Knopov & Seigel, 2018)
– 5 state racism index factors considered
– Correlation between level of state racism &
rate of unarmed Black people killed by police
– Data support aspects of both theories
37. Responses to police brutality
with limited to no success
• Use of implicit bias training inconclusive so
far (Maron, 2016)
• Diversifying police forces not very
successful (Cobbina, 2020)
• Body cameras have almost no effect on
behavior (Yokum, Ravishankar & Coppock, 2017)
38. Responses to police brutality
with promise
• Restrictions on use of chokeholds,
shooting at moving vehicles (Use of force Project,
2020)
• Preparing officers to support people with
mental illness with robust training (Calahan,
2020)
• Demilitarization of local police forces
(Delehanty, Mewhirter, Welch & Wilks, 2017)
39. Other suggested responses to
police brutality
• Re-negotiating police union contracts to
increase officer accountability (Bokat-Lindell, 2020)
• Eliminating “qualified immunity” for civilian
deaths (Brown, 2020)
• Initiating a truth & reconciliation process
about police abuses (Bokat-Lindell, 2020)
40. Other suggested responses to
police brutality
• Hiring more police officers (Bokat-Lindell, 2020)
• De-funding police departments (Ray, 2020)
• Hiring social workers to replace many police
functions in existing police structures (Singer,
2020)
• *Not* hiring social workers for work in police
departments as it will not change underlying
oppressive culture (Vakharia, 2020)
41. Discussion questions
1. How is police brutality a form of structural
racism?
2. How can social workers best respond to the
problem of police brutality at micro, mezzo
and macro levels?
3. Are there alternative conflict & dispute
resolution systems that we can foster to
avoid police involvement in “hot situations?”
42. Action steps:
• Educate yourself about how police
brutality gets made (Brooks, 2020)
– BIPOC: Tend to racial trauma, foster resiliency
– White people: Don’t ignore problem because
you can
• Speak up about what’s happening in your
community (Hao, 2020)
• Consider investing in positive community
supports & programs (Davis, 2016)
43. Action steps:
• Learn trauma-informed practices for work
with youth in urban communities due to
over-exposure (Geller, Fagan, Tyler & Link, 2014)
• Participate in anti-racism work in your
organization! (Kendi, 2019)
• Engage in anti-racism work on *yourself* &
spread the message! (Saad, 2020)

Editor's Notes
Welcome to the #SWEduActs teach-in on police brutality as a form of structural racism. A teach-in is a general educational forum on any complicated issue, usually an issue involving current political affairs. The main difference between a teach-in and a seminar is the refusal to limit the discussion to a specific time frame or a strict academic scope. We are a group of social work educators from around the United States who came together to amplify how police brutality and structural racism are addressed in the curricula within our Schools of Social Work.
I am dedicating this talk to a Black male social work professor colleague who has experienced the ills of what police brutality can do to a community because I want social work students to know that police brutality touches our community too. And it is important to note that all Black male social work faculty are not immune depending on their social histories and social locations. He wanted me to emphasize to you that the social work response to police brutality should be as real and as serious as the brutality itself, so let us keep that in mind as we learn today. It is our ethical responsibility to empower ourselves to be on the frontline of addressing police brutality and being courageous in confronting structural racism.
Law enforcement in the United States is made up of about 18,000 federal, state, county, and local agencies.
Alicia Garza, Patrisse Cullors, and Opal Tometi
A Vigil in Memory of Black Women and Girls Killed by the Police. For the first time, family members of Black women killed by police came together from across the country for a powerful vigil designed to draw attention to their loved ones' stories. The family members of Alberta Spruill, Rekia Boyd, Shantel Davis, Shelly Frey, Kayla Moore, Kyam Livingston, Miriam Carey, Michelle Cusseaux, and Tanisha Anderson were present and supported by hundreds of attendees, activists, and stakeholders.
