This is a general question and answer forum, you would need to consult an attorney face to face to answer all your questions.
As Ms. Holton suggested, the type of answers you can get on a forum such as this are limited, especially given the complex nature of your post, so you should definitely consult with an attorney. Use the Find a Lawyer tab to find one in your area. That said, you should also be aware that governmental agencies and employees in California have a lot of different immunities that could apply to your situation, especially the immunity for discretionary acts when exercising authority vested in the employee. Also, there is a requirement that a claim be filed within six months of the incident giving rise to the claim, and this is a mandatory prerequisite to filing a lawsuit against a public agency in California. So, you need to consult with an attorney who can analyze your situation and determine if you have a case that can be pursued, as well as help you through the claims process. Best of luck to you...

I suggest you look for attorneys here who do personal injury. If you contact me then I can refer you to someone else who does this kind of litigation.
This answer is not legal advice and does not create an attorney-client relationship.
