The component parts of crimes. For example, 'Robbery' is defined as the taking and carrying away of property of another by force or fear with the intent to permanently deprive the owner of the property. Each of those four parts is an element that the prosecution must prove beyond a reasonable doubt.

A rule of evidence that disallows the use of illegally obtained evidence in criminal trials. For example, the exclusionary rule would prevent a prosecutor from introducing at trial evidence seized during an illegal search.

The money posted by a 'bondsman' for a defendant who cannot afford his bail. The defendant pays a certain portion, usually 10%. If the defendant fails to appear for a court hearing, the judge can issue a warrant for his arrest and threaten to 'forfeit,' or keep, the money if the defendant doesn't appear soon. Usually, the bondsman will look for the defendant and bring him back, forcefully if necessary, in order to avoid losing the bail money.

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.

Someone who delivers an item of personal property to another person for a specific purpose. For example, a person who leaves a broken VCR with a repairman in order to get it fixed would be a bailor.

An order signed by a judge that directs owners of private property to allow the police to enter and search for items named in the warrant. The judge won't issue the warrant unless she has been convinced that there is probable cause for the search -- that reliable evidence shows that it's more likely than not that a crime has occurred and that the items sought by the police are connected with it and will be found at the location named in the warrant. In limited situations the police may search without a warrant, but they cannot use what they find at trial if the defense can show that there was no probable cause for the search.

A court appearance in which the defendant is formally charged with a crime and asked to respond by pleading guilty, not guilty or nolo contendere. Other matters often handled at the arraignment are arranging for the appointment of a lawyer to represent the defendant and the setting of bail.

A trial that ends prematurely and without a judgment, due either to a mistake that jeopardizes a party's right to a fair trial or to a jury that can't agree on a verdict (a hung jury) If a judge declares a mistrial in a civil case, he or she will direct that the case be set for a new trial at a future date. Mistrials in criminal cases can result in a retrial, a plea bargain or a dismissal of the charges.
