It's a lot about cues. Ping the bell as it were. Like when they kept showing that same chick in the mass shooting footage, until we "saw" her.
Their level of illicit conduct being SO frikn' over the top criminal and horrible does king of act as a barrier to being caught. Obviously a person who claims such a "conspiracy theory" is really happening is mentally perverted somehow for even thinking of such things.
The cue is to just call it the phrase and suddenly we are removed and protected from the possible truth and it's horrific nature. It's a quick way out for the public to just change topic and go to a happy place, which is pointing a finger at crazy people.
