many cops don't know the law. one cop in my town didn't know that law about assault. he thought physical contact was required but in fact contact escalates the incident to "battery". you can be assaulted without physical contact if you are in fear. yes it's only verbal but it is a crime. someone can also become violent and not touch you, as-in punching a wall, kicking a chair, etc. one cop in the police office didn't know that but another did. go figure. my Dad once said 75% of people are only barely adequate at their jobs.

BTW I was very impressed with your correctness on the road and seemed not to break any rules. also that you and the cop were both polite to each other. interesting that he was behind another motorcyclist and given that special situation if you were a few inches over to the right you and the motorcycles could have shared the lane more easily. very cool tweet by the PD though, huh?
