WASHINGTON The Supreme Court is again trying to clarify what the long-established Miranda rights require the police to do, with the justices on Wednesday agreeing to decide whether officers can interrogate a suspect who said he understood his rights, but didnt invoke them.
The high court agreed to hear an appeal from Michigan prosecutors who had their conviction of Van Chester Thompkins thrown out by the 6th U.S. Circuit Court of Appeals because police kept talking to Thompkins after reading him his rights despite Thompkins not verbally agreeing to invoke or withdraw his Miranda rights.
