Former Boston Police Commissioner Ed Davis, who was at the helm during the marathon bombings says the biggest concern now is what terrorists have already done in Sochi. “You’re concerned really about pre-positioned assets,” Davis said. “If the bombers had a plan, you worry about what’s there an what’s been prepositioned.”

That’s something Congressman Bill Keating is asking about while on a trip to Moscow. He says information sharing between the US and Russia has tailed off after the Marathon Bombing Investigation. “In the efforts beyond that, sharing information generally in the war against terror, that’s not at the level the marathon bombing information is being transmitted,” said Keating.
