My friend drives a 2011 Ford Mustang (Premium V6 model) and was next to a Chevy Cobalt at a stop light. The Cobalt preceded to peel out at the light, and my friend gently accelerated. The cop was 2 blocks down, and out of sight. He pulled both of the cars over, and preceded to give them both a citation for drag racing. He has a court date set in late July? Do we need a lawyer? What evidence can we gather to help our case?
