It would be unconstitutional for the Congress to pass laws taking full oversight of state and local police (it&#x27;s not one of the Congress&#x27;s enumerated powers, and per the Tenth Amendment &#x27;The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.&#x27;).<p>Sometimes police are found to have violated federal civil-rights law, but that is a bit of a sketchy backdoor.<p>The Right Thing would be for each state to create such a commission, and for the Congress to create one for federal law-enforcement agencies.
