I used to work in a prison in Georgia where the executions were performed. Even though they used injection, they kept the electric chair for historical reasons.
I’ve witnessed many executions although nobody really saw the executions as the final minutes were behind a glass window covered with a curtain.
What really was ironic was the fact executions were performed by injection not for humane reasons but because Georgia power (the state electrical provider) didn’t want to be linked to the deaths of criminals. Yet, they cut off the power to the elderly across the state yearly during the winter because the poor couldn’t afford to pay their bills which caused many of the elderly to freeze to death.
