Bulger says FBI deal gives him immunity

Cites long-ago pact with FBI; trial moved back to March 2013

Gangster James “Whitey” Bulger plans to argue that he had an agreement with the FBI, forged four decades ago, that protects him from prosecution for any crimes committed during his reign as a mob boss, including the 19 murders he is accused of participating in.

The defense team’s legal strategy emerged Monday in court papers filed in Bulger’s federal racketeering trial. Also Monday, at a hearing in federal court in Boston, his trial was pushed back four months, to March 4, after his lawyers complained about the complexity of the case.
