Exculpatory Evidence: Typically used in criminal cases, this type of evidence is that which favors the defendant, either partially or totally removing their guilt in the case. In the United States, if the prosecutor or police have found evidence, it is their duty to disclose it to the defendant.
Inculpatory evidence is evidence that shows, or tends to show, a person's involvement in an act, or evidence that can establish guilt. In criminal law, the prosecution has a duty to provide all evidence to the defense, whether it favors the prosecution's case or the defendant's case. Evidence that tends to show a person's innocence is considered exculpatory evidence. For example, if a man is poisoned to death by an overdose of arsenic, and a bottle of arsenic is found in the purse of his wife, that bottle could be considered inculpatory evidence against his wife.
