Yes. For clarification.... already moved out of where the movie was playing... Thus not disturbing anyone watching the movie.
Maybe trespassing, depending on what was said etc.
But any cop who cannot remove a couple of teens from the lobby of a movie theater without pepper spray should be fired for being a 'girlie man.'
So clubbing them with a night stick would be preferable? Did you know that mace does less harm and is required to be the first physical response?
