Was there a warrant or not, and if there was one, did they or did they not produce it?
CASE CLOSED. Sue the city and the cops involved should be terminated immediately.
You are right. It is human nature that we learn best from the most painful and or expensive lessons. Law enforcement will only learn to take our rights seriously if cases where they don’t cost them significant pain. Sue the department for enough to make them feel it, and terminate the officers involved. This goes beyond the usual screw up that would just mean an administrative punishment. Need to set an example for remaining officers. The lady should think about a civil suit against the guys too.
