I live in a decent town with a low crime rate...

Our police department also has a good response time, less than two minutes last I heard.
Since I've lived on this street, now going on seven years, the cops have been called out four times - once because a home robbery was in progress, once because a car was broken into, and two because two residents were chasing their wives with hanguns (I am so not kidding either, different families too). I have a lot more to fear from the legal firearm owners on my own street than I do from criminals at this point.
