While this sounds just like the gun nuts want life to be, it turns out to be wrong on many levels. In the first place, running after the guy and shooting uselessly into society is dangerous to everyone but the criminal.

In the third place, this is a perfect example of the uselessness of armed citizens trying to stop crime. This is something that ought to be left to the pros.
