Sean Hannity clucked over the "irresponsible speculation on the part of the left" over who was behind the Boston Marathon bombings. But, as I've often said, whatever Hannity complains about in others is an almost certain sign that he's about to do or condone the same behavior in others. So when "Mr. Mayor," Rudy Giuliani, told Hannity that his "hunch" is that bombings were "homegrown" - and then suggested they were done by a Muslim, Hannity was all ears.

Giuliani said:

None of us know what's behind this. Is this ideological? If it's ideological, is it Islamic terrorist? Is it some other kind of ideology? Is it some crazy person? We're gonna find that out. If you go by the odds, I mean, how often have these things been done? Then, of course, you're gonna lean in the direction of it's somehow Islamic-related, jihadist-related, just given the percentages of the number of bombings that have taken place.

Giuliani is wrong about that. Going by the numbers, the chances are that it's not. As CNN noted last year:

A study by the Institute for Homeland Security Solutions, a research consortium in North Carolina, found that from 1999-2009, in the United States there were 17 al Qaeda-inspired plots undertaken, 20 plots initiated by white supremacists and 17 by violent anti-government militants.

Hannity speculated, "It may be homegrown."

Giuliani continued:

My hunch? This is homegrown. ...I don't think this is orchestrated by Al Qaeda or any of their offshoots in Africa or other places from there. I think, frankly, if it was, we would have picked it up because it would have had to have been communicated internationally and the coverage now is immense. Sounds to me like this was more homegrown. Like (Muslim) Major Hassan. ...This is my hunch, I could be absolutely wrong.

He could be absolutely right, of course. Or it could be some other kind of homegrown terror plot. Later, Fox reporter Jennifer Griffin offered up more evidence to Greta Van Susteren to back up the homegrown theory. But you can rest assured that if Hillary Clinton or Barney Frank said the same thing, the Fox talking heads would have exploded.
