U.S. Sen. Lindsey Graham sharply criticized law enforcement’s information-sharing system during the probe into the deadly Boston Marathon bombings, Business Insider reports. 
Graham said the system should have picked up on the suspicious activity of bombing suspect Tamerlan Tsarnaev.
Graham also urged federal agencies to “up our game.”
“When one of these guys goes into the system and they leave the country, we need to make sure where they’re going and interview them,” Graham said on CBS’ “Face the Nation” on Sunday.
“And when somebody in the database like this begins to openly interact with radical Islamist websites, an FBI agent should knock on his door and say, ‘You told us before that you wanted to be an Olympic boxer. You love this country. What the hell is going on here? We’re watching you.'”
