Not always.
The first murderer in “In Cold Blood” to be excited hung for half an hour and didn’t die...
Singapore does proper hangings because they get the practice. They would probably train us just for actual expenses because they like Americans.
Three firing squad members will be behind the wall, with rifles facing the inmate through the opening.
The rifles and open portal will not be visible from the witness room. All three rifles will be loaded with live ammunition.
The witnesses will see the right-side profile of the inmate. The inmate will not face the witness room directly. The electric chair faces the witnesses directly.
The inmate will wear a prison-issued uniform and be escorted into the chamber.
The inmate will be given the opportunity to make a last statement.
The inmate will be strapped into the chair, and a hood will be placed over his head. A small aim point will be placed over his heart by a member of the execution team.
After the warden reads the execution order, the team will fire.
After the shots, a doctor will examine the inmate. After the inmate is declared dead, the curtain will be drawn and witnesses escorted out.
