I'm not sure about this, but if this movie is being filmed outside of city limits, what's to stop him from saying that he's just playing a game of airsoft and video taping it? Phone the cops to tell them that you're going to play a small game of airsoft and jsut start taping?
Don't do this until verified by by men better than myself.
"He resisted. I asked him to comply."
"Telling him to 'eat it, bitch' is not really a request."
