Re: Mindset
If there's any point in drawing and quartering after shooting, your firing squad needs urgent training.
Not necessarily, remember, they dug up Cromwell in order to execute him for treason.

Geez I guess a bit of history lesson as well as the obvious redundancy should be in order.
There are a few cases where you have redundant methods of death performed. Primarily as a way to desecrate the corpse. Or to send a signal that you really wanted the person dead.
Remind me how William Wallace was killed?
[Hint: He was hanged, drawn and quartered—strangled by hanging, but released while he was still alive, emasculated, eviscerated and his bowels burned before him, beheaded, then cut into four parts.]
Just to save you from going to Wikipedia.
