I only count on myself for home protection. I live a little ways out in the country. Any type of confrontation would be well over with by the time the police made it there. Which is why I have a 12 guage pump action with bird shot (won't go through 2 layers of sheetrock), a Browning (Belgian made)30-06, and a Kimber .45. I'm pretty well covered.
There is a vacant house next door to me, where the previous owner died a couple years ago. Anything fishy goes on over there, I'm out at the fenceline, making my presence known.
I guess I wouldn't feel right about NOT doing anything about it.
