Rudy Giuliani, who was mayor of New York City during the 9/11 terrorist attacks and helped lead the the massive recovery efforts there, discussed the Boston Marathon explosions and the government methods of preventing future terrorist plots Tuesday on CNBC.
Saying in the aftermath of 9/11 that he and other government and police officials expected many more attacks of that nature, he praised the response of the government to terrorist acts as being "much, much better now."
"We've prevented many, many attacks," he said. "If we hadn't changed the way we gathered intelligence, if we hadn't done the Patriot Act, if we hadn't done a few things like that, we could have had a dozen attacks. Twenty, 30 were stopped ... Intelligence gathering today is much, much better. However, if you get either a lone wolf or self-described jihadist who's operating maybe with one, two, or three people, it's very, very hard to pick up that intelligence."
