Definitely, if there is a cop on the premises who's job it is to patrol the premises, then to me that signifies that several incidents must have occurred in the past to warrant that, or the school is in a bad enough part of town.
If it's just a regular ole security guard, then that's normal and I wouldn't care. A cop patrolling a school is definitely not normal.
Then Toronto is pretty bad, eh?
