The only way you get Justice in this case is if federal prosecutors charge Duarte with violating the truck drivers civil right under the guise of police authority. It's highly probable he would not have committed this crime if he wasn't a police officer. 
It's also hard to understand how dragging someone from their vehicle and beating them unconcious is not a felony offense. Someone obviously told corrupt prosecutor Kaneshiro to keep it misdemeanor and don't press for jail time. Whitewash this thing so Duarte can switch to DLNR or DPS like the child rapist cop did.
