Would bum-rushing a shooter like Orlando be the best thing to do??

I don't get it. 49 dead (not counting the shooter), and another 50 wounded. That's 100 people that got shot. If HALF of those people had rushed him, he would have never been able to shoot more than what he had in a single (or double, if he was shooting a gun in both hands) clip. Yes, people would have still died. But not nearly so many as did. Someone would have gotten to him as soon as his clip was empty, if not before. And then they'd pile on. If I thought I was going to die anyway, I'd like to think I'd at least try to get the bastard. Is it time that we start telling people to rush in situations like that? Would you?
