I read your reply as "He was a weapons instructor and therefore cannot burn a fuse and go on a psychotic rampage". I believe that is what the exchange was about before you replied. The question people are asking is "Why did he have guns" and not "How was he trained to use them".

That's not what I'm saying. He had a pretty good "why" for having easy access to weapons until he was checked into a mental institution. If he was a danger to himself or others I bet they could have prevented him from getting weapons. I'm interested to see why they chose not to or how their attempts failed.

I admit it was a deviation from the subject and might have been confusing. Every time this guy's background is brought up people tend to think military training is some forbidden knowledge that citizens don't have access to, which isn't the case at all.
