After speaking with the chief of police, the officer who stopped me, and a lawyer, we've all come to the conclusion that yes, it was a case of excessive force. The officer took a split second glance, and "panicked" No I'm not sue happy, I got my apology, even though I could take it to court, win, and "fuck the police" I'm not. At the end of the conversation, we even had a laugh at the fact that officer aggression needs a chill pill. Although I did get a pretty decent bruise on my chest/shoulder. No harm done.
