Don't blame us, Putin insists as he claims Russia had no 'operational value' on Boston bombers

Summary: Russian President Vladimir Putin said there was no intelligence of "operative value" his security agencies could have passed the U.S. authorities about the two ethnic Chechen brothers accused of bombing the Boston marathon. "Due to the fact that the Tsarnaevs had not lived in Russia for many years, our security services could not provide information which had operative value," he said Thursday.
