Their neighbors can't be to smart, no game only has 1 or 2 gunshots.. I mean they can't really think theres a war going on next door can they?
Very possible, ever been in a neighborhood with a drug dealer? The guy next to my house down in Tajunga, CA when I was somewhere between 6 and 10 was a major drug dealer, there was a police raid on the street, whether it be his house, the manufactoring plant across the street, the church, etc. and gunfire was a pretty common experience. Gotta love LA, eh?
