Tracy also promoted a crisis actor conspiracy theory of the Boston Marathon bombing . Conspiracy theorists have claimed such attacks are " false flag operations " staged by 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
