I need to know the statue of limitation in florida where can

You should help your brother in filing a complaint with the local sheriff. I think the SOL in Florida is for four years. You have to activate a fraud alert with the individual credit bureaus on the suspicious accounts. Anyone using your brother's credit fraudulently will be stopped and you will be informed about it. After you have taken these steps, contact the creditors and inform them that your brother does not owe these accounts. Their has been a fraudulent use of his credit and that you request a review.

I want to know what is the statue of limitation on filing a complaint against the police and what is the statue of limitation for filing a lawsuit against the police.

How long do I have to sue someone in small claims court for a vehicle accident

Not sure on that. It should be covered under Tort law. Try researching here:
