You do not have to pull the trigger that results in killing children to be insane. Any way you slice it, murdering children is insane. Aiding and abetting those who ultimately do murder children is, in my opinion, in absentia insanity. From you, the selfish voter who votes for the crooked politician who supports the NRA, the organization that encourages mass murder to be commonplace by supporting Colt, the manufacturer of the AR-15, the weapon the mass murder, to the user of the AR-15, the trigger-puller, makes you insane by complacency and complicity of an insane, murderous act. The mass murderer cannot exist without difficulty because you catalyze the chain of death that ultimately results in the final unit of death to occur, the unit being: gun + handler. You cannot have a gun murderer without the gun, you cannot have the mass murderer without the automatic weapon; they are joined at the hip. You, the voter, have indirectly placed the AR-15 in his hands. His act categorizes him as insane but your act of allowing him to execute his act of insanity is also insane. You are the invisible component of that vehicle of murder.
Legally, criminal insanity is understood as a mental defect or disease that makes it impossible for a defendant to understand their actions, or to understand that their actions are wrong. A defendant found to be criminally insane can assert an insanity defense, but you, having initiated that chain of death, have no such defense.
