6. There were at least four failed opportunities to prevent this tragedy before the day it happened.

I agree with you and would add these five points of failure.

-- In 2004 for shooting out tires he should have lost his guns and ownership rights.

-- In 2010 the same thing for discharging a firearm, which was clearly loaded and improperly stored.

-- His employer should have screened and eliminated him from candidates for employment or severely limited the terms of his employment.

-- And the Navy should have screened him and banned him from entering any of their property.

So simple.

Yet the focus by many ends up being how to kill the second amendment or otherwise prevent anyone and everyone from getting even a basic pump shotgun.

Crazy world.
