The American Civil Liberties Union and the public defender's office have raised concerns about investigators' plans to interrogate the surviving Boston Marathon bombing suspect without reading him his Miranda rights.
The Massachusetts Federal Public Defender's office said it will take the case of 19-year-old bombing suspect Dzhokhar Tsarnaev. Public defender Miriam Conrad said there are "serious issues" regarding the interrogation.
ACLU Executive Director Anthony Romero says the legal exception applies only when there is a continued threat and is not open-ended.
It is not clear when Tsarnaev will be able to answer questions. He is hospitalized in serious condition and under heavy guard after being arrested Friday night following a daylong manhunt punctuated by gunfire.
