Hello gentlemen, this would be cmptrdewd's dad. If you would like to contact the police prior to a game, go for it. In my 11 years as a Phoennix Police Officer, (and no I don't know everything), a call about an airsoft game would be met with a don't do it. Not only that but, the info would never get to the street officer for that beat anyway. Maybe other cities would treat this situation differently, but as for Phoenix it would cause more trouble than it would help. If you see the Police, put down your airsoft and tell them you are playing a game, not a problem. Have fun and take care...
