Here's a new take on the "Sheep, wolves, and sheepdogs" analogy by my favorite university professor, who is also a certified gun nut.
There are many people who find it odd that I shoot firearms on an almost daily basis with other sheepdogs like my good friend and occasional bodyguard, Barry Whitehead. They would certainly find it odd that we compare notes over who fired the most shots through the same hole in the head of an Osama Bin Laden target. And, needless to say, they would certainly not understand why I kill literally hundreds of live animals per year (usually small varmints) in order to perfect my skills in hitting targets that actually move.
But the wolves are still out there and we do not know when they will attack. But they will. And, for most of you, the sheepdog is your best and only hope.
