What needs to happen to them is what the French did to the killer of General Jean Baptiste Kleber in 1800...They tied him to a tree and slowly burned his arm down to the bone (hmmm...I wonder if that hurt?). Then they impaled him up the ass on a post and left him to die, which I read took several hours. Then they shipped his head to France where his skull resides to this day in the Museum of man with the words “Criminal” written across the top.
I like that.
Also the rack is a good idea. You are strapped to a table and stretched, the bones snap, it takes hours for it to happen, then you slowly bleed out because every vein and capillary is broken, don’t want an artery that would be way to fast.
