On 3-14-08 I was pulled over for not having a front license plate. I was driving a 93 Toyota pick up with dealer plates. After realizing they were dealer plates and they came back clear and clean I should have been left alone because when you are running dealer plates they issue only one plate per vehicle for the rear of the vehicle. To this day they refuse to give them back. Is this not a violation of my right to due process? If something can be done to remedy this situation please give me a call.
