Not sure I follow. How is a handgun "predictable? Does it not depend on outside variables?? Like the skill of the handler , the emotional state of the one handling the gun. The surroundings themselves?? Don't guns jam sometimes?? Maybe I have been watching too many CSI and crime stories ;-)
Sure, Guns rely on outside variables to work, however, how isn't it predictable. "Pull trigger to shoot, just remember the Safety is off." Pretty predictable to me, Oh and about the Guns that jam; that's generally from improper cleaning.
My money is on the well trained dog. (NOT a pitbull or something equally overly aggressive. That is not even a consideration) HEck.........even a small dog trained to alert on unusual sounds , would be fine by me. Yappy ones can do the job quite well.
Wow, You honestly believe that there are "overly aggressive" dogs. though i am not surprised that you would label a pit bull as one, considering your stance on guns and the people who own them. I mean honestly, it's not the dog it's the owner. Honestly, you should stop while your a head.
