This footage comes to us from Birmingham, Alabama, where we see a police cruiser physically ramming a vehicle involved in a so-called exhibition driving event, which I take it means just doing donuts mostly, while people film. This officer is now under investigation by the Birmingham Police Department. Is that legal? Can a police officer ram a vehicle doing donuts, or whatever else “exhibition” driving consists of? What constitutional rights are at play?
