Blackiequine, I don't think I've ever had any satisfaction from calling the police (just see if you ever get anything returned after a burglary, for instance). However, as I said, I would have called them on this occasion as they're better equipped to deal with it than anyone else.
If they turn up. I remember watching the riots on TV a few years back, seeing buildings burning, and wondering if any of the emergency services would ever turned up. They did, next day.
