Responding to Garland, Norad45 and NightHiker:

Maybe I'm stating the obvious, but don't we all take calculated risks everyday? As has been said many times before on this board, on a purely statistical basis, the most dangerous thing we do everyday is get into our vehicles and drive around. We know the risks involved, do the best we can to lessen them and take our chances.

If I know I will be in a high crime/dangerous area, I will take appropriate precautions, but if I'm just out and about on my usual routine, I've put the weight/size vs. odds of needing onto the scale and for me at least, the .22 wins.
