On July 21, 2013, I got a red light camera ticket that I was not aware of until the DMV sent me a letter telling me that if I do not pay my ticket, my license would be suspended. I paid the ticket and sent a letter to the judge, asking to reopen the case and to have a retrial. I got a letter from the court and my trial was granted for 03/25/2014, but because I do not know anything about this ticket, I was looking to send a discovery letter so they can send me the photos of the camera and any other evidence they have. Some people told me to send it to a district attorney, while others told me to send it to the police department, the judge, or the persecutor. Please advise me where to send it, what to put on the letter, and how it should look. Thanks in advance.
