The privilege that allows the president and other high officials of the executive branch to keep certain communications private if disclosing those communications would disrupt the functions or decisionmaking processes of the executive branch. As demonstrated by the Watergate hearings, this privilege does not extend to information germane to a criminal investigation.

The earliest and most common test for criminal insanity, in which a criminal defendant is judged legally insane only if he could not distinguish right from wrong at the time he committed the crime. For example, a delusional psychotic who believed that his assaultive acts were in response to the will of God would not be criminally responsible for his acts.

Evidence that proves a fact by means of an inference. For example, from the evidence that a person was seen running away from the scene of a crime, a judge or jury may infer that the person committed the crime.

A crime consisting of physical contact that is intended to harm someone. Unintentional harmful contact is not battery, no mater how careless the behavior or how severe the injury. A fist fight is a common battery; being hit by a wild pitch in a baseball game is not.

The killing of one human being by the act or omission of another. The term applies to all such killings, whether criminal or not. Homicide is considered noncriminal in a number of situations, including deaths as the result of war and putting someone to death by the valid sentence of a court. Killing may also be legally justified or excused, as it is in cases of self-defense or when someone is killed by another person who is attempting to prevent a violent felony. Criminal homicide occurs when a person purposely, knowingly, recklessly or negligently causes the death of another. Murder and manslaughter are both examples of criminal homicide.

The well-known term for an Alien Registration Receipt Card. This plastic photo identification card is given to individuals who are legal permanent residents of the United States. It serves as a U.S. entry document in place of a visa, enabling permanent residents to return to the United States after temporary absences. The key characteristic of a green card is that it allows the holder to live permanently in the United States. Unless you abandon your residence or violate certain criminal or immigration laws, your green card can never be taken away. Possession of a green card also allows you to work in the United States legally. Those who hold green cards for a certain length of time may eventually apply for U.S. citizenship. Green cards have an expiration date of ten years from issuance. This does not mean that your permanent resident status expires. You must simply apply for a new card.

An affirmative defense to a crime. Self-defense is the use of reasonable force to protect oneself from an aggressor. Self-defense shields a person from criminal liability for the harm inflicted on the aggressor. For example, a robbery victim who takes the robber's weapon and uses it against the robber during a struggle won't be liable for assault and battery since he can show that his action was reasonably necessary to protect himself from imminent harm.

A serious crime (contrasted with misdemeanors and infractions, less serious crimes), usually punishable by a prison term of more than one year or, in some cases, by death. For example, murder, extortion and kidnapping are felonies; a minor fist fight is usually charged as a misdemeanor, and a speeding ticket is generally an infraction.
