I'm not the kind of person who would complain to the police at every opportunity. Having said that, this guy is actually associated with the Toronto Police Service, and he tried to 'order' the driver behind you to take an illegal action that would have put you in significant danger. I think it's a good idea to at least call the relevant division and let them know what happened. I find that crossing guards confuse the situation at intersections more often than they help. If the driver behind you was one of the idiots who just act on what they're told without thinking, you could have easily been run over.

On an unrelated note, when did the police service take over responsibility for crossing guards? I actually had to look that up before I could believe it! When I was a kid, that was the school board's responsibility.
