Gang Activity

The U.S. Supreme Court held in United States v. Abel [416 U.S. 45 (1984)] that the prosecution may impeach a defense witness based upon the witness’s reputed membership in a prison gang. Likewise, a defendant in a criminal trial should be able to impeach a prosecution witness based on the witness’s reputed membership in a police gang. Membership in a deputy gang is particularly impeaching because there is substantial evidence that deputies are bound to cover up misconduct and lie on behalf of fellow deputies.

A gang is defined as an ongoing organization, association, or group of three (3) or more individuals, whether formal or informal, who:

  • Collectively or individually are involved in criminal activity or anti-social behavior; and,
  • Claim a common name, color, symbol or dress.

Gang activity ranges in severity form “bullying” to drug dealing and drive-by shootings. These groups thrive on intimidation and notoriety. Dependent on both individual and group participation, these groups can vary in structure from non-formal leadership to highly structured. Gangs will identify themselves with names they take from various places including streets, buildings, bands, or even popular movies.
