Now, dispersed drive-in campgrounds in the National Forest and BLM land are another matter. The vast majority of criminals will never get far from a road.
Tell that to the creep who spent his summer vacation raping and murdering young couples backpacking the Appalachian Trail some years back. Again, watch the Discovery channel long enough and they'll show it again.
Frequency of criminal activity in the boonies is no indicator of intensity.
I'd be willing to bet the lethality rate for the victim when being attacked by a violent armed criminal in the wilderness is over 90% (number pulled out of the air).
I fail to see how much trouble a S&W airweight would be to carry.
Big enough to give a black bear second thoughts, even if less than lethal, and certainly big enough to give bipedal varmints a nasty shock.
