The mental element in the commission of criminal acts--intent--is discussed and illustrated with examples portrayed from investigating officers' perspectives. Criminal intent is defined as the resolve or determination with which a person acts to commit a crime. Three types of criminal intent exist: (1) general intent, which is presumed from the act of commission (such as speeding); (2) specific intent, which requires preplanning and presdisposition (such as burglary); and (3) constructive intent, the unintentional results of an act (such as a pedestrian death resulting from the actions of a negligent driver). Each instructional section of the tape is followed by a brief fill-in-the-blank test; answers are provided for instructors and are given to trainees by the tape. Questions include applications of the penal code to specific types of criminal acts and classification of specific crimes by the type of intent ivolved. The package is designed to be used for individualized instruction. A workbook which includes the tests, a posttest, and an overview of the unit is provided along with test keys for the instructor's use.
