Evidence Tracking
Evidence is essential to solving any case and proving the guilt of an offender in a court of law. Once a crime has been reported the first step of the responding officer is to secure the crime scene to ensure it is properly preserved until forensic investigators can arrive on the scene. The evidence collection process begins with thoroughly documenting the crime scene. The process begins with a walk through of the crime scene in order to identify potential evidence and to develop an idea of what occurred at the crime scene. Once the evidence has been identified the evidence collection process will begin with collecting evidence that is fragile or easily damaged or destroyed.
In the rape scenario DNA evidence is crucial to proving a crime occurred and showing the guilt of the offender. Rape cases are hard to prosecute and require physical evidence to prove the act of rape even occurred. In a majority of cases it is the word of the victim against the word of the perpetrator. DNA evidence can provide conclusive evidence that a sexual assault occurred and point to the guilty offender. In the rape scenario evidence that was located and will need to be collected is the semen on the comforter and the tissue located in the trash can. This evidence can contain valuable DNA that points directly to the offender. The semen and the tissue can contain the DNA profile of the offender and the tissue.
The evidence collection process begins first by identifying the evidence in a walk through and then properly documenting the evidence. Documenting the evidence is an essential step in the collection process. This begins with photographing the evidence where it sits in order to show the court where the evidence was located and in what condition. Once the evidence has been photographed it must be collected using uniform collection standards. The comforter that was located contained a semen stain that must be collected in order to develop DNA on the criminal suspect. Most items of evidence will be collected in paper containers such as packets, envelopes, and bags and liquid items can be transported in non-breakable, leak proof containers (Schiro, 2006).
When collecting DNA from the comforter the forensic technician will mark the wet stain with a permanent marker in order to make it easier to locate during the DNA analysis. The technician will then wait for the comforter to air dry before placing it in a clean package and properly sealing and documenting for transportation. The second piece of evidence that was located at the crime scene was a tissue in a waste paper basket. The tissue will need to be collected using a pair of tweezers or using a pair of gloves and then be placed in a plastic container. The plastic container will need to be sealed and then properly documented for transportation.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Crime Scene Vocabulary
3. Testimonial evidence includes oral or written statements given to police as well as
court testimony by people who witnessed an event.
Physical evidence refers to any material items that would be present at the crime
scene, on the victims, or found in a suspect’s possession.
Trace evidence refers to physical evidence that is found in small but measurable
amounts, such as strands of hair, fibers, or skin cells.

What will evidence collected at a scene do for the investigation?
• May prove that a crime has been committed
• Establish key elements of a crime
• Link a suspect with a crime scene or a victim
• Establish the identity of a victim or suspect
• Corroborate verbal witness testimony
• Exonerate the innocent.
• Give detectives leads to work with in the case
Types of Evidence
4. POLICE OFFICERS are typically the first to arrive at a crime scene. They are
responsible for securing the scene so no evidence is destroyed and detaining
persons of interest in the crime.
The CSI UNIT documents the crime scene in detail and collects any physical
evidence.
The DISTRICT ATTORNEY is often present to help determine if any search
warrants are required to proceed and obtains those warrants from a judge.
The MEDICAL EXAMINER (if a homicide) may or may not be present to
determine a preliminary cause of death.
SPECIALISTS (forensic entomologists, anthropologists, or psychologists) may be
called in if the evidence requires expert analysis.
DETECTIVES interview witnesses and consult with the CSI unit. They
investigate the crime by following leads provided by witnesses and physical
evidence.

Crime Scene Personnel
5. Step 1: Interview
The first step in investigating a crime scene is to interview the first officer at the scene or the
victim to determine what allegedly happened, what crime took place, and how was the
crime committed. This information may not be factual information but it will give the
investigators a place to start.
Step 2: Examine
The second step in the investigation of a crime scene, which will help identify possible
evidence, identify the point of entry and point of exit, and outline the general layout of the
crime scene.
Step 3: Document
The third step in the protocol involves creating a pictorial record of the scene as well as a
rough sketch to demonstrate the layout of the crime scene and to identify the exact
position of the deceased victim or other evidence within the crime scene.
Step 4: Process
This is the last step in the protocol. The crime scene technician will process the crime scene
for evidence, both physical and testimonial evidence. It is the crime scene technicians
responsibility to identify, evaluate and collect physical evidence from the crime scene for
further analysis by a crime laboratory.
