What percent of mass shootings and other acts of terrorism are due to extraterrestrial consciousness commandeering and directing the actions of a person’s physical body to carry them out?

This is fully 50% of all such crimes, big and small, occurring worldwide. Because such behavior is illogical and felt naturally to be attributable to mental derangement, whether or not there is a formal psychiatric diagnosis, the authorities will look no deeper for explanations and often will end the investigation right there if there are no obvious connections to an organization involved in such undertakings because of political extremism and so forth. If this is a lone wolf, so to speak, who is apprehended or killed in the act of an unfolding tragedy, they will be assumed to have become unbalanced and gave in to dark impulses impossible for the normal person to fully comprehend, as mental illness is a mystery to this day, even to the medical establishment. But all know the signs, symptoms, and consequences that can happen when people become out of control, acting on dark inner thoughts and delusions that distort their thinking and may seek drastic action to serve their inner compulsions. This is so frequent as to be commonplace and receives little afterthought at this point because people are so accustomed to this happening, they simply accept there are significant numbers of demented people in the populace, so one can simply expect this to happen. This further reinforces the conclusion that the only defense is to take away as many weapons as possible because nothing can truly be done to affect human thinking and mental health, particularly when people do not seek treatment and identifying them comes too late to take any kind of preventive action. So you can add this to the long list of crimes committed by the Extraterrestrial Alliance to create trouble in human society and drag everyone down because of it.
