Holy Shit

I don't know what is happening, car accident? But like 4 or 5 cop cars just flew past sounding like they were going 110 mph and had the sirens on the top speed (if that it the right term) - like super loud and the siren seeming to go faster the more they accelerated. Does the siren speed up when they accelerate? Whatever... something is happening in Somerville, wonder if it will make it on the news?
