Boston Marathion Explosions

He has the right to remain silent, and Boston Marathon bombing suspect Dzhokhar Tsarnaev has exercised that right after he had been giving the FBI valuable information about the attacks.

FOX News Radio's Jeff Monosso reports:

Terror suspect Dzhokhar Tsarnaev was talking at the hospital in Boston  saying he was recently recruited by his brother, but after the judge showed up and he was Mirandized Tsarnaev invoked his right to remain silent.

The FBI apparently furious. Saying the termination of the interrogation may have put the country in danger.

The FBI also says based on text messages sent, the mother knew her older son had been radicalized, willing to die for Islam.

And we've also learned the FBI and the CIA were both warned in 2011 by Russia that the older brother posed a serious threat.
