Yes, I think hidden string pullers are behind most multiple shootings.
What is funny to me is we know sonic weapons are out there. Even CIA agents are hit with them overseas now. We also know psychopaths are a real phenomenon, and intelligent ones often rise to positions of power.
But look at the way society has programmed people to not even consider psychopaths and sonic weapons might have met up in the US somewhere, and produced something that could be a problem.
Note that the CIA agents hit with Sonic weapons complained that when they came back to the US proper, they were hounded here on US soil, with their houses broken into, and they saw people following them.
