A crazy guy shoots over 100 people, 50+ of which are dead, and you guys are worried about:
1) whether it was legal for him to buy a gun? As if, had he bought the gun illegally, it would somehow make a difference? - insane
2) how people expressed sympathy for the deceased and their families. Apparently it's disingenuous if there are religious undertones? - insane
3) whether he was a "radical" Muslim? - he acted alone, so what?
Crazy psychopaths do crazy horrible irrational crap. It's not a matter of policy, unless you're talking about mental health, which none of you are.
