Here in King Co., WA, there's all sorts of noise. A creep wanting to shoot a gun off has a pretty good chance of going undetected right about now. One of my nervous greyhounds is standing next to me, panting like she's run 3 sprint races, because she can't handle the noise. Wussy[>(]
I used to work in the downtown ER in Fresno, CA about 10 yrs ago, and every year we'd hear gunfire and security would find fired bullet shells on hospital grounds - shots fired at the hospital. I don't know what that ever accomplished.
