Even if you have a legal right to do something (e.g. taking a picture or standing on a street corner), you don't necessarily have a right to sue the police officer for a wrongful arrest. Police officers and other government employees enjoy considerable immunity from their acts in the course of their job, unless they act with a particular type of intent; the level of intent (purpose, knowledge, or recklessness), I believe, depends on the state jurisdiction. For Constitutional issues, I imagine it depends on whether you're suing the individual personally or the state agency, and lots of other things.
