Finally, a sensible method of execution of murderers.
You pick six shooters and hand them rifles and tell them one is loaded with a blank.
You can construct the Walter White method using a bump stock with a timer on a
trigger bar or just a trigger bar attached to several rifles and timer mechanism.
Nobody has to fire the shot. Or you can attach a rope to a helmet so when the
subject falls asleep and his head drops - BANG. Or he can choose his own
moment. - BANG Or if he sneezes - BANG.
A loaded rifle has considerable recoil, a blank has none.
