Who is he with, really?

"Like almost everyone else in the crowd of fellow travelers and detractors who come out for and against him — sometimes both — [Brandon] Darby is more unreliable narrator than cynic. Certainly he comes across as a grandiose believer in his own propaganda, whether as the founder of the militant grass-roots aid movement Common Ground, created as a response to support survivors of Hurricane Katrina, or as the disillusioned turncoat and FBI plant who egged on, then turned in a group of young hotheads plotting to disrupt the 2008 Republican Convention in Minneapolis."

According to a former associate, it was Darby's savior complex that moved him to rush south to aid a Katrina-imperiled friend, then stay in New Orleans to help out other survivors and found the Common Ground relief collective. And perhaps his difficulty with father figures caused him to tell a police officer who asked what he was doing in the area that "I'm trying to foment social change" — then later bond so deeply with an FBI handler that he readily sold out an amateur cell of would-be terrorists trying to rig up Molotov cocktails using tampons.

To his mostly embittered associates on the left, Darby is variously a fallen hero, an attention-seeking egomaniac and a full-on Judas. Absolutist that he is, Darby now excoriates the FBI for insufficient vigor in prosecuting child prostitution. Today he's a Tea Party darling and a passionate columnist for the website Breitbart.com.
