So black people think they can just walk up to President Obama's house (that is, the White House) and ask, "Is Barack home?"
Come on man.
64 year-old Alfred Brock from Louisiana attempted to do just that. He was subsequently handcuffed and searched after letting the Capital police know he had a firearm in his truck. Clearly, this isn’t a case of a possible assassination, just a good old fashioned "Pop Up". Take your meds, Alfred.
