A "crisis actor" is a term describing a hypothetical actor who participates in a false flag event such as a bombing or mass shooting simulated by the conspirators —usually government or corporate forces— in order to achieve some goal such as justifying increased government surveillance, disarmament of the population, or military action against blamed nations or groups. Crisis actors are claimed in this context to play the part of bystanders or witnesses, emergency response personnel, and (with the aid of stage makeup) wounded victims of the attack.
Robbie Parker, the father of Sandy Hook shooting victim Emilie Parker—after doing a televised news interview on the day after the shooting—became the target of conspiracy theorists, who claimed the interview was staged. It was alleged he is a "crisis actor" and was "getting into character" before going on televised news to grieve over the loss of his child.
