"The Nazis did discover many new things like hanging kids under 12 did not kill them but slowly strangled them over the course of a full day."

No new discovery there Donuel.

Ever heard of the old sentence handed down - "To be hung without mercy"?

Back in the days when children were executed weighs used to be attached to their ankles so that there would be sufficient weight on release of the trap to break the neck cleanly and quickly. The weights were called "Mercy".

The means by which offenders in Iran are now publicly executed ensures a long slow death by suffocation as the rope round the neck of the person to be executed is attached to the bucket of a digger and the person is hoisted into the air to be strangled slowly by his own body weight - apparently that is the will of Allah, according to Sharia Law.
