Lorenzo Adamson, a 15-year police veteran, says he was stopped in his car on May 30 for not having a license plate.

The suit alleges that officers inexplicably jumped onto Adamson’s back and tried to choke him before tackling him to the ground. Adamson was charged with resisting arrest and vehicle code violations. The charges were dropped.
