Willy...
Are you sure someone isn't putting something in your tea
....you are digging a lot of big holes lately...maybe it's just an age thing ??....or are you being mischevious again
I would make one small point....
If somebody half-crazed on drugs, with a knife or a gun, and is attacking somebody in your family...how the heck do you plan to kill them...with your bare hands, or the yard brush....you wouldn't even get close before you too became a victim.
That the Law allows you to kill them is right and proper......how you can manage it is yet another story.
Give me 2300 ft/sec from a 0.223 and I dont care whether they are running towards me or away....they wont ever do it again !!!!
