behind a desk
In theory the cop could have cited the motorcyclist coming up behind him for speeding. However, the motorcyclist didn't pass him.No he wasn't. The guy was speeding, the cop could have turned on his lights and pulled him over. But instead, the cop decided to try to brake check motorcyclist. That's murderous road rage when done to a motorcyclist.
In practice, "I didn't pass the cop" will get that tossed by a judge almost immediately so cops usually don't bother.
This cop was out to cite for more than just a speeding ticket.
