Lethal injection - They sterilize the needle... why? lol. It's not painful at all. They put you to sleep, then inject a chemical mix that stops your hearts. 5-10 minutes later they call the death. There have been a few cases where people had to be injected twice and the doctor on scene called death but the prisoner woke up shortly after (very, very sick, but still alive). In my opinion, lethal injection is too humane. A murder, rapists, ecetra should experience some pain in death... like they did to their victims.

Firing squad - They do not get paid insane amount of money. Usually they simple take a few guardsmen who went through a few extra classes. Their is no standard on the format... some people use all rounds, some people use x rounds mixed with blanks. There has been one case that I know of where death was by bleeding out instead of a straight kill shot. Still too humane in my opinion if the guards are dcent shots.

Hanging - too quick and clean unless the nooseman miscalculates the weight... too humane.

Electric chair - Gets a little messy... but efficient and painful if the ampage is done correctly. There has also been a few cases of survivors here as well.

Drawn and quartered - my personal favorite... done over several days, perp kept alive as long as possible with carterization.

Life sentence prisoners cost over $90K+ a year per inmate. This includes room and board and in most places - a gym, cable tv, etc. Not all lifers are in a maximum security, etc.

A bullet costs about 2 cents.... I'm just saying.
