I was traveling north on Mack, past Cadieux, this afternoon around 3:45 when 6-7 police cars came barreling by at [[least) 60 MPH with lights flashing and sirens blazing. As I continued north, two more passed by and turned on Moross. I didn't see any of them after that. Nothing about it on the 4 p.m. news. Any idea what's going on? [[My initial reaction, which I hope is not right, was that the only thing that would get that kind of a response would be an ' officer down' call.)
