I’ve always thought lethal injection was too much of a medical procedure in appearance and should not be used for executions.
Hanging by raising the condemned up off the floor to strangle in the noose would usually be over in minutes but don’t even check the guy for half an hour. There would be no need to find a vein and they would need no fancy trapdoors.
The fact that he beat the victim
The fact that he shot the victim and laughed
The fact that he shot the victim again (2nd time)
The fact that the victim was buried ALIVE and breathing, and he knew it.
I agree , he should have recieved the same tratment as he gave out !
