My question involves police conduct in the State of Arizona. In March of this year I was arrested and charged with theft. Before the police arrested me, they entered my dorm room. They deny ever having entered into my room in the report, and they didn't have a warrant. But two of my friends saw them, and all of us (there were five of us across the hallway in my friends dorm) heard them.

They didn't obtain any evidence. Can I pursue legal action against the police for the violation of my rights? Or are a few witnesses not enough to prove police misconduct?
