Well, since you seem to love Dr. Hererro, you might wan to actually read him (he was one of those I was referencing earilier):
"Canadian bear biologist Dr. Stephen Herrero reached similar conclusions on the basis of his own research, which suggests that
a person�s chance of incurring serious injury from a charging grizzly bear doubles when bullets are fired rather than when bear spray is used."
That's about as kindly as I can put it...
