I’ve watched about as much as a sentient being can stand of cable coverage of the FBI’s announcement of suspects in the Boston Marathon bombing case– an hour or so– and in that time Chris Matthews kept hinting that the suspects are Arabs. He wondered whether the FBI doesn’t have ethnographic experts who can say on the basis of facial features whether these guys are from a foreign country, and he promptly offered Yemen as a possibility. Later he pressed experts about his suspicion that the suspects are foreign. They put on new baseball caps to try to “hide their identity” and pretend to be Americans, he said. They’re political zealots, he said in so many words on another occasion– not the kind you find in America. I don’t see what evidence he has for these assertions. In fact, they seem unfair.
