I actually caught, well almost caught, a burgular in my car.
Short story is he was faster than me and the best I could do was throw a golf club after him as he ran away, of course I missed.
I had made a concious decision not to carry a gun because at the time I went looking I was only suspicious of some noise.
Well, after I discovered a live target it was a good thing for me, and for him, that I did not take a gun with me. There is absolutely no doubt I would have emptied a clip into his back as he tried to run away. First shots would have been from about 5 ft. away.
When I discovered him I was so enraged that there is no doubt I would have shot him, shot him dead if possible. Even if he went down I most likely would have fired some more for insurance. Make no mistake, I wanted to kill him.
Unfortunately, under those circumstances, I would have probably received the worst of the legal issues in a court of law.
The fact that he got away clean bothers me to this day when I think about it.
