George Black

Collins' superior in the A.T.F. Chicago office, George Black is, in fact, part of a gun-running operation which he co-ran with Edward Haints, an Illinois assemblyman running for mayor in Chicago under a gun-control platform. It was Black who had contracted Natasha Radinov to kill Jonathan Washington, the only witness to the operation, for which he provided her with a cardkey with Collins' ID, as well as Rally and May for helping Collins. He also supplied Radinov with the use of a supposedly shut-down A.T.F. safehouse for her to stay in. (From Wikipedia)
