I feel terrible for the people familes as well.
I would never run - I would have shot the SOB down as soon as he opened fire. They shouldn't have taken matters into their own hands - that is what the police are for. Usually not a good idea to confront some one who had a loaded firearms - esp NOT an a paramiltary one.
I was hunting on private property once in CT up in a tree stand - three guys come down a hill and they see me (they are trespassing since I my buddy told me he hadn't given any one permission to hunt). One of them must have had a new rifle since he was showing it to another guy. What does this guy do?! He points the FK'n thing at ME while looking thru the scope! I leaned/curled around the tree and started yelling at them and figured if I got shot by "mistake" I wasn't going to be too happy. They couldn't understand why I was so mad at them>!?#
After that my friend posted his land and local EPOs patrol the roads on a routine basis (guy lived up the street). I hunt another spot now much more secluded. I always use a flashlight going in and out. I can see, but I want to make sure some yahoo knows it is a person and not a deer.
People do WEIRD things when they get "cornered".
