GUNS AND GRUB Outside the notoriously violent cafeteria where tensions ran high-including the ever-present racial tension between black and white inmates who already ate separately-stood an armed guard station. The barrel of a 30-ought rifle poked through one of the holes drilled into bulletproof glass sent a warning to inmates that rounds would be fired if things got out of hand. In the event of a riot, the two guards aiming those rifles shot to kill. Two more guards stood watch inside the cafeteria, but unlike their peers, they weren't protected by a pane of flexible glass that could stop a 38-cartridge. Despite toting rifles they knew to keep their eyes trained on the crowd, especially the table of convicts positioned just outside the gun port, which had been designated for the prison's worst offenders.
