In order to understand mass killers, we need to stop looking at them as a unique phenomenon. They are simply suicidal young men.
That's right - suicidal.
The mass killing is merely a fantasy, an ideation concocted in order to bring about the ultimate desire... their own death.
I'm not open to any new gun laws, but I am open to refining the ones we already have, and here's my idea.
#1 - Flag anyone who ever self-harms, or expresses suicidal ideation as unfit to carry or own a firearm. This would require a trial by a jury of peers if the person losing their right demands it.
#2 - Lift some of the HIPAA laws when it comes to mental health. Gun vendors should see flags if a person has any suicidal marks in their record.
#3 - Lower or remove the idea of "Sealed Juvenile" records. If you are committed to a mental hospital at 16, that should stay on your record. It shouldn't magically disappear when you turn 18.
All of this, in combination with arming and hardening our schools and other soft targets, will go a long way towards making a safer America.
