05 August 2005 :

an anti-government extremist was executed for the 1993 shooting death of a police officer who was gunned down as he approached the man's car.
George Sibley Jr. nodded to relatives, stared at his victim's family and gave a final statement of defiance before he was put to death."Everyone who is doing this to me is guilty of a murder," Sibley said after being strapped to a gurney for the lethal injection. Sibley, 62, was convicted of capital murder for the slaying of police officer Roger Motley. Sibley's common-law wife, Lynda Lyon Block, 54, was executed in 2002 for her role in Motley's death.
The officer was gunned down in a Wal-Mart parking lot in Opelika when he approached the couple's car. A passer-by had said a child in the vehicle had been asking for help. Block's 9-year-old son was in the vehicle as she and Sibley emptied their guns into Motley and his patrol car.
The pair claimed they shot the officer in self-defense after he touched his holster. At the time, the two were fleeing from Orlando, Fla., to avoid sentencing on assault convictions in the stabbing of Block's 79-year-old former husband. Both Block and Sibley had been active in fringe political groups and renounced their U.S. citizenship, claiming the courts were biased and without jurisdiction.
They tried to cut their ties to the government by getting rid of their driver's licenses, car registrations and birth certificates.
