Click on this WGST 640 link and the first link in the upper right (as of this posting) to hear a Texas man call 911 because his neighbor's house is being robbed, then go out and shoot one of them in the yard.
A-C-E doesn't advise this, but it is good, ole-fashioned Texas justice. It's how neighbors used to take care of each other and their property. Potential robbers were deterred by knowing they couldn't count on having time before the cops arrived.
That story ends a lot better than this one.
