Almost Shot

So I was at my friend's birthday party the other day. He was going to do an airsoft thing at his church. It was private property, all permissions were granted, etc. I get there, and after a while, we start playing. All is well till about the 1 1/2 hour point. Then we hear sirens. At first I thought "...it cant be for us can it?" but sure enough, it was. Around 7 or 8 squad cars flew to the church, and pretty soon we were surrounded by officers with shotguns yelling at us to get on the ground and show our hands. Long story short, since we were on private property and all, they let us go. Needless to say, we just played cod for the rest of the night.
