Here in Tucson, two teens in a stolen car try to rob a man, and one robber dies and the other is injured and arrested.

And in Traverse City, Michigan, a lunatic stabs 11 people, but stops when an armed citizen throws down on him. Good video, BTW. Here’s more on Derrick Perry, the citizen who captured him, although the story says Perry somehow did so “using a store shelf as cover,” while the video shows Perry holding a handgun, not a store shelf.
