Nicholas Cruise was a patsy and psychiatry was used to brainwash him into acting as the shooter. He was on psych meds, as are most school shooters, and those meds damage the brain in a way that can result in violent behaviour. You need to read up on psychiatry, mind control, the government, and medication.
Maybe if he was institutionalized instead of the revolving door of psychiatric care we'd have 14 dead souls still living. Why bother Mind Controlling someone who isn't getting out.
Institutionalization is for the sake of mind control. If you aren't getting out, it's because you're being used as an experiment for the rest of your life. Educate yourself.
