Supreme Court releases Ky. lethal injection protocol.

Supreme Court releases Ky. lethal injection protocol. Kentucky's execution protocol is now public after the U.S. Supreme Court ordered its release as part of a case challenging lethal injection. The protocol had been kept secret until today, when an edited version was filed publicly on order from the high court. Kentucky's lethal injection protocol is similar to that used in 35 other states. The 16-page protocol details everything from rules for visiting an inmate once an execution order has been signed to how to reverse an execution if it is halted once the drugs have started flowing.
