SCADs are 'State Crimes Against Democracy' and tend to be called 'conspiracy theories' by those in power who wish their backdoor dealings and collaborations to remain secret along with their culpability.
9/11, Iran-Contra, Watergate, various assassinations...the list of SCADs and suspected SCADs gets longer all the time and goes back to LBJ's and McNamara's Vietnam and before.
And you know what they say when you have thorny problems to root out: you must first identify demons in order to fight and vanquish them.
