If police are hassling you for say videotaping them, and they attempt to arrest you, can you resist without being charged for resisting? Also, if an officer begins to assault you without cause, can you defend yourself and detain them as you would with a "normal" person? It seems police can unjustly strip us of our rights and detain/arrest us for things the constitution permits, yet there is no recourse. Police are also using excessive force both with reason and without reason and don't get disciplined. Could someone perform a citizen's arrest on an officer brutalizing an individual or else acting against the Constitution?
