If confronted with this scene, I've always planned to beat a perp senseless with my Pelecan 1400 case; empeg inside. Fragle, pah. The empeg would survive, the perp wouldn't.

Seriously, though, I wouldn't have realized what was going on until 15 minutes later. Sad.

More seriously, though, I wish citizens could step up to the bad guys. So much fear of retaliation; justified at that. If the citizens were strong enough, the crooks might just fear them. Nice to dream.
