A condemned murderer in Georgia could become only the second person whose execution is videotaped, US death penalty researchers have said.Andrew DeYoung is scheduled to be put to death by lethal injection on Thursday evening for murder.
Another condemned man hopes to record the execution as evidence that lethal injection causes pain and suffering.
But prosecutors argue the video would jeopardise security plans and could end up being leaked.
DeYoung, 37, was convicted of stabbing his parents and sister to death in 1993 over an inheritance.
On Monday, a Fulton County Georgia judge ruled that death row inmate Gregory Walker's lawyers may have a team videotape DeYoung's execution.
Walker has filed a lawsuit challenging his own death sentence on the grounds that the state's cocktail of lethal injection drugs illegally causes pain and suffering.
Prosecutors have objected to the proposed recording.
On Thursday, Georgia Attorney General Sam Olens sought permission to petition the state Supreme Court - just hours before DeYoung's scheduled execution.
"Executions in this state are not public, and the potential for sensationalism and abuse of a videotape of an execution is a great concern," the attorney general's office has argued.
Walker was sentenced to death in 2005 for the murder of a 23-year-old hotel maid who had stolen drugs and cash from him as he slept in a hotel room.
