What are some state police powers?

The State, either State or federal, has practically no police or law enforcement powers that any citizen does not have. All of the authority, privileges protections to use force, detain suspects, compulsion to obey laws, filing of charges with a magistrate, etc. are powers also reserved to the People. Police, Sheriffs deputies and other professional law enforcement officers have been delegated this natural right by the court but the rights and powers of the police are no greater than those of everyday citizens.
