The American Civil Liberties Union says it's concerned the surviving Boston Marathon bombing suspect will be questioned by investigators without being read his Miranda rights.
Dzhokhar Tsarnaev remained hospitalized Saturday after being wounded in a firefight with police Friday. His brother was killed earlier.
U.S. officials say a special interrogation team for high-value suspects will question Tsarnaev without reading him his Miranda rights, invoking a rare public safety exception triggered by the need to protect the public from immediate danger.
ACLU Executive Director Anthony Romero says the exception applies only when there's a continued threat to public safety and is "not an open-ended exception" to the Miranda rule.
Twin explosions near the Boston Marathon finish line Monday killed three people and wounded more than 180. Tsarnaev's father calls him a "true angel."
