Cut off by a cop car

Okay, I meant to write this the other day but forgot. I don't remember for sure which night this was, but I know it was dark or almost dark. We had taken the campus shuttle back to the dorms. It drops people off in the parking lot across the street from the dorms, so when you get off the shuttle, you turn right, toward the back of the shuttle, and start walking. You walk a bit in the parking lot and then cross the street.
Well, when we were finishing the parking lot section and stepping into the street, a car flew right in front of us. Pasta didn't have to back up, but she slowed down to almost a stop so it could pass safely in front of us. And, I swear, it looked like a cop car! It was black and white with what seemed to be something written on the white driver's side door. A cop car cut us off! All I can say is, it better have been chasing someone down to have done that to us, but I doubt it since its sirens and light weren't on.
I just thought it was kind of crazy that a cop car did that. We've been cut off by lots of cars before or had lots of cars speed up and then end up stopping at the last minute so we can cross here on campus, but we've never been cut off by a cop before. Crazy!
