Crisis Actor

A crisis actor (aka actor-patient or actor victim) is a trained actor, role player, volunteer, or other person engaged to portray a disaster victim during emergency drills to train first responders such as police, firefighters or EMS personnel. Crisis actors are used to create high-fidelity simulations of disasters in order to allow first responders to practice their skills and help emergency services to prepare and train in realistic scenarios as part of full-scale disaster exercises.[1][2][3][4][5][6] The term has also been used by conspiracy theorists (conspiracy theory) who claim that some mass shootings and other terror events are staged for the advancement of various political objectives such as to advance gun control measures. https://en.wikipedia.org/wiki/Crisis_actor
