How do you ever tell the difference? I hear noises that I think are gunshots at least once a week, but my neighbor insists they are always fire crackers. As far as I know, what I have heard has yet to be a gunshot because I never read about shootings in the local news. However, I used to live in places where sounds that I thought were gunshots turned out to actually be gunshots, so I don't want to get complacent just because I live in a "safe" place now.
Basically, how do you ever tell the difference and how do you know when to call the cops?
