Lack of sirens

about an hour ago i was on my way out, driving down my street doing about 60 as i usually do..(its a 40 zone). Anyways as im aproaching the end of the street and theres this guy in a golf that burns out out of a driveway. i was the only car there, he couldve waited... but thats not the point of this post. Naturally i slow down to keep a distance, and not cut it close cuz this guy cut me off. The thing that gets me is that a cop comes flying out of the entrance to the subway like 20meters down the road without any siren, and cuts me off as well. There were parked cars blocking the view pretty well so if i had gotten on the gas i probably would have gotten side swiped by this cop. anyways... it pisses me off when cops do shit like this. they race around my hood during the day/night... and rarely uses their sirens....

does it bother anyone else that they dont use sirens like half the time... or is it only in toronto that this occurs on a regular basis?
