I am sorry to hear about this situation. To sue in a state court, one needs to have a "cause of action." There are numerous causes of action, such as "breach of contract," "negligence," "fraud," "unjust enrichment," etc., as well as causes of action rooted in statutory law. Every state has their own although they are very similar to each other in every state because they all stem from the same common law. A pleading in Court needs at least one cause of action, although it is not unusual to have more than one.
The closest cause of action I can think of in such a case may be negligence. Negligence is defined as (a) an existence of duty, (b) breach of that duty, and (c) injury as a result thereof. Bowen v. Lumbermens Mut. Cas. Co., 517 NW 2d 432 - Wis: Supreme Court 1994.
Now, the battle would be to prove to a Judge or Jury (unless this is settled) that the police did not perform, or significantly under-performed, their duties. This is hard to do, as one would essentially have to show sluggish action, lack of care, etc. A lot of this would be subjective and up to the jury to decide. In addition - since this is a government agency - one would have to prove GROSS NEGLIGENCE or MALICIOUS action in order to hold a stage agency liable (state agencies enjoy higher liability protection). This may be even harder to do.
Whether or not one feels that this is worth the effort is of course, up to you.
Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal.

I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
