First, you should file a complaint with Internal Affairs of the police department. Second, you have a very limited time to file a claim against the City of Oakland, Oakland Police Department, and each police officer that you specifically know of in this case, Does 1 through 100, (these are people that you find later in the case). Government Claims must be filed within 180 days, and that means weekends count, or you lose your right to sue. Once you have filed your claim you preserve your right. The City and OPD will have to either accept your claim and pay the amount of damage you are claiming, or reject your claim. Once your claim is rejected, you can then sue, but remember, you must file that claim as soon as you can on a special Government Claim form which you can get from the City of Oakland Risk Management Department. Second, talk to attorney John Burris in Oakland, as he does civil rights violations and is excellent. If you were ordered out of the house, and went outside but still on your property, you were not in public. You may have been in public view, but not in public, and you must be in public to be arrested for being drunk in public. Now, if you live in an apartment or condo where stepping outside puts you in a common walk way, then you are in public, but if it is a house, and you step outside but not on to the side walk and are still on the property, you are considered not in public and that would be an illegal arrest. I cannot stress this enough, you have a very limited window to file your Government Claim Form or you lose your right to sue, so get started immediately. Make appointments with attorneys immediately, and have all your documents copied and with you so you are not wasting time. Some of these attorneys work on a contingency basis with you paying costs, and others strict contingency.
