'I oversaw murder' - former head of executions for US state on campaigning against the death penalty
The man who was in charge of executions in the US state of Georgia tells us why he's now campaigning against the death penalty. Allen Ault oversaw deaths via the electric chair in the 1990s until he left his post as corrections chief in 1995. He now describes the practice as "horrific" and has received counselling to try to come to terms with his sense of guilt.. Several years later the state of Georgia stopped using the electric chair and switched to using lethal injection. 30 people in Georgia have been killed by lethal injection since 2001.
