Crim Law Flashcards
3 elements of a criminal offense
Actus Reus
Mens Rea
Cause
Actus Reus
Defendant engaged in 1 or more specific acts. An act can be an affirmative action or the omission of an action that the defendant had a legal duty to.
Mens Rea
Acting with the specific intent or awerness required of the crime. There are 5 levels of Mens rea:
1) Purposefully: with the specific intent to do the crime or the specific intent to act without intending the result
2) Knowingly: defendant knows of a specific set of facts or circumstances while engaging in prohibited act, regardless of knowledge they are intending the results
3) Recklessly: conscious disregard for substantial or unjustifiable risk that the act will have a result
4) Negligently: should have been aware but wasn’t of a substantial and unjustifiable risk of causing something prohibited by law
5) Strict Liability; generally presumed against unless there is clear legislation in support of the public welfare.
Mens Rea of Specific Intent crimes
Specifically intended the result. Versus the general intent to act but not specifically commit the crime.
Causation
Actual proximate cause of an unlawful event. The event must be the foreseeable probable consequence. Any intervening causes must not be reasonably foreseeable.
2 Types of Criminal Defenses
Ones that negate the Mens Rea and Affirmative Defenses
Defenses that negate the Mens Rea
Mistake of fact or law: available for specific intent crimes where a reasonable mistake stops the defendant having the appropriate mens rea. Ignorance of the law is not an excuse unless knowledge of the crime is an element.
Impossibility: defendant intends to commit the crime but facts make it impossible
Intoxication: some specific intent crimes, usually only valid if the intoxication was not caused by the defendant, must show that the defendant was tricked, did not know, or was an unforeseen reaction
Mental Disorder: defendant may use this defense or insanity to raise a lack of mens rea defense against any crime requiring intentional or knowing
Affirmative defenses
Burden belongs to the defendant to raise affirmative defenses.
Insanity, Avoiding greater harm, Self-Defense, entrapment, consent, alibi
Insanity
Defendant is insane as a result of mental disease making them incapable of knowing what they did was wrong, minority view is that because of mental disease, defendant could not resist the impulse to do something wrong. The model penal code asks if defendant lacked the capacity to conform or appreciate the significance of their actions.
Avoiding Greater Harm
(necessity test) defendant must have committed a crime to imminent harm, there must have been no reasonable alternative, and the harm caused was less serious than what would have happened.
Self-Defense
right to use force to protect against another’s use or unlawful threat of force when the defendant actually and reasonably believes defensive force is necessary. Only deadly force justifies deadly force. some statutes may require defendant to have retreated if at all possible. Defendant can never be the cause of the need to use defense.
Homicide 1st Degree
First degree murder is the intentional killing of another person by someone who has acted willfully, deliberately, or with planning. A premeditated intent to kill requires that the defendant had intent to kill and some willful deliberation (the defendant spent some time to reflect, deliberate, reason, or weigh their decision) to kill, rather than killing on a sudden impulse.
Homicide 2nd Degree
Second-degree murder is typically murder with malicious intent but not premeditated. The mens rea of the defendant is intent to kill, intent to inflict serious bodily harm, or act with an abandoned heart (e.g., reckless conduct lacking concern for human life or having a high risk of death). Showing an indifference to human life.
Felony Murder
The felony murder rule is a law in most states and under federal law that allows anyone who is accused of committing a violent felony to be charged with murder if the commission of that felony results in the death of someone. The people involved in the felony may be charged for murder under the rule even if they had no intention of killing someone.
Manslaughter
Manslaughter is the act of killing another human being without malice. It is a general intent crime that is distinct from murder because it requires less culpability.
Voluntary manslaughter is intentionally killing another person in the heat of passion and in response to adequate provocation.
Involuntary manslaughter is negligently causing the death of another person.
