Hmm. For the record, you have not clarified your point ("statistically the odds of being accidently (
sic) shot by an idiot like my old roomate (
sic) who was a paranoid freak before the cocaine and a paranoid super freak after are vastly, vastly higher than ever being involved in a Cho like situation"), just that you consider your roommate abnormal.
I just searched google news for stories of college students wounded/killed in a negligent discharge.
Since 2011, news.google.com returned one hit.
2011 at Florida State.
The map shows it off campus, but the gun owner was a FSU student.
This was a
rifle negligent discharge, which is not easy (but would count for purposes of your premise).
It happened at 1:16 am Sunday morning.
(Gee, you think?)
Okay, so there is one case in point.
I suppose it would be out of bounds to ask if your roommate ever had a negligent discharge. Being a "paranoid super freak" would seem to put him in a high-risk category (meaning, statistically abnormally likely to have a negligent discharge) when it comes to negligent discharges.
Again, I'm not saying they do not happen, I am just challenging your premise that statistically one is more likely to be shot by a negligent discharge than an active shooter. I just don't see the evidence. Maybe you consider the premise to be simply an article of faith.
