Former mayor of New York City Rudy Giuliani joined John Gambling to discuss the explosions at the Boston marathon, drawing knowledge from his experience in dealing with 9/11 and being present at the London bombings in 2005.

Giuliani shared that in past attack investigations officials have purposely kept information under wraps in an effort to fly under the radar while attempting to catch a suspect.

"The only thing I know from having conducted many, many investigations with the FBI and the NYPD including terrorism investigations," said Giuliani. "More than a few times they put out false information, and I think it's perfectly legit. If I was looking for somebody that I didn't want to leave Boston - or America - I would sure as heck not want them to know I'm two minutes away from catching them."

John took the opportunity to ask Giuliani what we should expect at events and attractions going forward - are we going to go into lock down?

"Heck no," said Giuliani firmly, not hesitating to revert to the same attitude he had after the 9/11 attacks. "Please come to New York as a way of showing terrorists that they can't affect our behavior. Basically stick it in there face and say, 'The hell with you, you're not going to stop us from being Americans, you're not going to frighten us.'"
