Quick reminder: Steve Emerson, a self-dubbed expert on terrorism, said yesterday that "there are actual cities like Birmingham that are totally Muslim where non-Muslims just simply don't go in".
But Emerson was a bit baffled when asked if he thought others might be offended by the suggestion that getting mocked online was comparable to getting waterboarded.
And just as Emerson had been getting criticised for his geography (and "sloppy research", he admitted)...
...his credentials as a terrorism expert also started to get challenged.
