There is nothing you can do unless you have that kind of money to prosecute a county employee. Having finger prints done cost mony. I'm not sure how wealthy you are but to be honest its not worth it. You would have to get a lawyer, pay court fees an so forth. It would be a lot easier to get a new SD card and maybe this time put the camera in a tree or hide it better this time.

Another thing you could do is call the better buisness beraeau and let them know. They would love to give them a hard time for you hands down.

If you went to the office and with just pictures and not actual proof of catching him in the act you can't do much. He will just deny it and be set free and keep his job. I would set one up on the opposite end watching that camera and see if he does it again.
