The ‘lone wolf’ gunmen in the USA are similar to Islamic suicide bombers – they are trained from a young age to commit such acts. Their lives are taken from them and they secretly suffer the ritual abuse that is required to train someone to do such things.
They are sacrificed for the purposes of those in power, who feel they have a right to take lives in this way.
Most people simply cannot do such a thing, because they have not suffered enough abuse and brainwashing as children. Also known as mind control (MC), these individuals are used for many purposes, depending on the talents they show as they are brainwashed.
Pop stars, individual sport stars (not team), spies, soldiers, and other killers. These usually require systematic brainwashing to achieve a high level of performance over a long period of time, without the rapid breakdown that normal people would usually undergo in the face of continued extreme difficulty.
