Yes thats true. Only one live round. And if it doesnt do the job. Someone walks up to them and shoots them in the headI thought there was a firing squad of 6, but only one has a bullet. They all aim and shoot. None of the shooters know who actually kills the criminal. Not sure where I heard /read this though.
And as for the slitting of throats being quicker. Those who are committing those atrocities are trying to inflict as much pain as possible and it would not be quick.
Apparently you can choose to sit, stand or kneel
ive heard conflicting stories that you can choose to be blindfoldered or not, but i think its not an option
Dont ask me how they work out if the bullet worked before they decide to do a shot to the head
