Cases based on crimes or litigation by or against individuals or groups can evolve into numerous types of demonstrations. For example if a case is based on race, religion, individual rights etc., there may be opposing factions who want to enter the court to support their views and those who are involved in the court case. Branch supervisors who are faced with this situation shall immediately activate their Court Security Contingency Plan and notify their Bureau Headquarters of the situation. Assistance may be dispatched from a local law enforcement agency or the nearest Sheriff's station.
