If you are saying that more access to medical records by (parents of adult children, gov't) might have helped, I beg to differ. The Patriot act allows DHS to access any medical record it wants and the HC provider cannot tell you that they gave you up to the feds. The ability to "perhaps" ferret out one nut at the expense of even more of our freedoms is to high a price to pay.
My two cents is that this is a product of something we will never understand. The Chevy Chase bank murders of 1989 were done by a former employee of mine. Some girl turned him down, he went home and got a handgun and killed three people. One of my other former employees called me from under his desk while it was going down.
The young man who committed the murders was never a problem. But let me tell you, everyone who had anything to do with him in any way did some serious thinking about our rolls after TSHTF. Bottom line, we all drew blanks. This was the path that the young man was following. We had no control over it at all.
Hindsight is 20/20.
Which raises a question. Just supposing you were in this situation, like in Aurora, an armored up crazy shooting people. Where are the weak points - if you had CCW, where would you aim ? (Assuming for sake of argument that there was no danger to anyone else present). Homes had body armor, crotch armor, head protection so, again, where's the weak points so you wouldn't be committing suicide to take him on? Reminds me somewhat of that episode in Calfornia where two bank robbers were "immune" to police firepower until a sniper got a neck shot.
