What happen when cops roll up to your urban sesh?

My crew and I were shooting a a rail at our local post office. The Police drove by twice and didnt even stop, we had 2 BIG spot lights by the way haha. Finally a community patrol came in and was like whaaat thats sick but you guys really cant be doing this here. He told us he would give us another hour to hit it again. He came back 1hour later and was like ok I wana see your footage this looks sick!! haha he was super stoked but then told us to clean up the snow we put in the entrance and that was the end of it.
