UPDATE

I asked about an "expert" about Saddam's half-brother's accidental decapitation and he was no help. He said that he was unfamiliar with the concept and didn't know how much force would be required to pop a head off like a child might do to a dandelion.


Future executioners

My "expert" is still only a med student so I'm going to cut him some slack. I'm guessing that this particular information is gained through on the job training.
