No Miranda Invocation for Boston Bombing Suspect

A special interrogation team for high-value suspects will question the surviving Boston Marathon bombing suspect without reading him his Miranda rights, U.S. Attorney Carmen Ortiz announced Friday.

Interrogators will invoke a rarely used public safety exception established by a 1984 U.S. Supreme Court ruling that allows authorities to question 19-year-old Dzhokhar Tsarnaev without invoking Miranda to keep the public safe.

The American Civil Liberties Union has questioned the decision not to Mirandize Tsarnaev, saying the public safety exception is not "an open-ended exception," reports the Associated Press .

While Ortiz made the announcement, the decision not to Mirandize Tsarnaev was likely made by the FBI in consultation with the Department of Justice, reports Slate .

Tsarnaev remains hospitalized with a neck wound sustained during the manhunt Friday.

By questioning Tsarnaev outside of Miranda, authorities hope to learn more about whether there was an overseas terrorist network behind the twin blasts that killed three and wounded more than 170 on April 15 at the Boston Marathon's finish line.
