there was a scotus case lately about this. pretty sure the police were covered under qualified immunity. my google fu is weak but it was in the past year.

cops (allegedly) stole $225000 but QI had them covered in the 9th circuit. scotus declined to pick up the case. for some background, the courts have declined to do anything about QI. they say it's legislator's job to fix it. odds are slim anything will happen.
