Admittedly, I didn't know all the details of this story. It seems that they indeed stopped the attacker with bare hands when his gun jammed. Just shows how much luck they had.

There are civilians lawfully carrying guns in Europe, just not many of them, so be free to already feel threatened. I'm not saying we should give guns to every kid out there, but if 1% of citizens were armed, shooting up 100 people wouldn't be such an easy endeavor.
