U.S. Criminal Law, Part II

  1. 1. Introduction to U.S. Law Introduction to and Overview of American Criminal Law:The Basic Elements, Defenses, and Constitutional Issues
  2. 2. Burdens of ProofBeyond a reasonable doubt Used in criminal casesClear and Convincing Evidence Used for special purposesPreponderance of the Evidence Used in most civil casesProbable Cause Used for arrest, search and seizureReasonable Suspicion Used for stops
  3. 3. Basic Elements of A CrimeLegality - legally proscribedActus Reus - human conductCausation - causativeSocial Harm - of a given harmConcurrence - which coincides withMens Rea - a blameworthy frame of mindPunishment - for which punishment is provided.
  4. 4. Legality and JurisdictionNo crime without law But whose law? A question of jurisdiction See PA Crime Codes §102There must be public respect for the law for it tofunction properly. Prohibition is excellent example of where the law didnt work because citizens didnt respect.
  5. 5. Actus ReusLatin (roughly) for “guilty act” Act - conscious, voluntary, and purposive behavior. See PA Crime Code §301Strict Liability Crimes Crimes where the act alone is sufficient to be in violation of law As opposed to “true crimes” which also requires “guilty mind”.Communication can be an action (inchoatecrimes)
  6. 6. OmissionGenerally failing to act cannot be punishedunless the law specifically creates a duty to actand the defendant has breached the duty. See PA Crime Code §302(b) (1) example – child neglect (2) example – where failure to act in accordance to duty created by contractual obligation leads to death.
  7. 7. Mens ReaLatin (roughly) for “guilty mind.” Complex and confusing because there could be 50 different definitions.Proving “mental state” is basically impossibleBest that can be done is to infer mental state Blameworthiness = responsibility + culpability Responsibility – free will and the three Is Culpability (see next slide)
  8. 8. Culpability (common law)Levels of Culpability under Common Law General Intent Specific Intent Strict Liability Intent Transferred Liability Intent Constructive Intent Scienter
  9. 9. Culpability (MPC)PA Crime Code §302 a person is not guilty of an offense unless he acted intentionally, knowingly, recklessly or negligently, as the law may require, with respect to each material element of the offense.Levels under MPC Purposely Knowingly Recklessly Negligently
  10. 10. CausationAn assumption that the act caused the thingbeing proscribed by criminal law is not enough.Must show a relationship between cause andeffect. Direct Cause Proximate Cause Intervening Cause Superceding CauseSee PA Crime Code §303
  11. 11. ConcurrenceAct + Intent + Result = Crime – DefensesPrinciple of Concurrence any act (actus reus) causing social harm must coincide, or be accompanied, with a criminal state of mind (mens rea). Normally intent comes first leading to the action.Motive must be distinguished from intent.
  12. 12. Defenses: failure of proofMistake of Law Rarely available, even if mistake was due to advice from attorney. Ignorance of the law excuses no one.Mistake of Fact Diminished Capacity IntoxicationSee PA Crimes Code §304
  13. 13. Affirmative DefensesDefensive ViolenceInsanity and Other Mental IllnessDuress, Necessity and Other Pressures on FreeWillEntrapment
  14. 14. Defensive ViolenceSelf-Defense must actually and reasonably believe there is imminent threat of serious harm or death. most courts hold no duty to retreat. only can use force necessary to prevent harmDefense of Others and Property Others – reasonably believed other person would have been justified to use force. Property – force necessary to avoid imminent theft or trespass.
  15. 15. Duress, NecessityDuress Crime committed under a threat of death or serious bodily harm. See PA Crime Code §309Necessity - Psychological pressure applied byanother Must face threat of harm Committing criminal act is only way to prevent No fault Criminal conduct involves less harm
  16. 16. EntrapmentSubjective Test Used in the federal system and a majority of states. Did idea for crime originate with police? Was D “predisposed” to commit the crime?Objective Test Did idea for crime originate with police? How would the average person react to offer by police? Focus is on police conduct
  17. 17. InsanityThe Right or Wrong Test mental disease results in failure to understand what they did or realize what they did was wrong.The Substantial Capacity Test lack substantial capacity to appreciate wrongfulness or to conform to requirements of the law. John HinkleyGuilty But Mentally Ill sent to prison, supposed to get treatment

  25. 25. Corporate Criminal LiabilityNew York Central: the birth of corporate criminalliabilityNot appropriate: when crimes cannot be punished by fines—since fines are the principle means for punishing a corporation—and when the crime, by its nature cannot be committed by a corporation (e.g, rape).
