re: 73 year old rancher shoots and kills illegal immigrant on his ranch.

the border area really has turned into a free fire zone as a result of the lack of control by the federal government. Put a 73 year old in the middle of that , with strangers crossing by his house in the middle of a remote ranch and sooner or later he will perceive a threat greater than he can control.

In the 1991 period, I was deer hunting on a ranch south of cotulla, texas when a group of 4 illegals come over the hill , one carrying a rabbit and one with a revolver. My response was to get out of the blind with rifle in clear site and stand behind a mesquite while they passed. 3 possibilities were likely before I exited
1. they would just walk on by
2. they would shoot at a presumed unoccupied blind
3. they would shoot at a presumed occupied blind

Was I threatened or threatening

The old guy in Arizona has to deal with that 7 days a week, every day of the year.
