Boston bombing suspect still hospitalized, guarded

BOSTON (AP) - 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 says it will take the case of 19-year-old bombing suspect Dzhokhar Tsarnaev. Public defender Miriam Conrad says 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's not clear when Tsarnaev will be able to answer questions. He's hospitalized in serious condition and under heavy guard after being arrested Friday night following a daylong manhunt punctuated by gunfire.

The London Marathon started Sunday with extra security measures in place to assure safety at the starting and finishing points of the event. It's the first major marathon since the bombings at the Boston one last Monday.

The London Marathon was expected to draw some 36,000 runners hoping to finish the course through London's streets.

A 30-second moment of silence was held before the start of the event to honor those injured in the Boston Marathon. Many runners wore black ribbons to honor the victims.
