Hand cuff him to a treadmill at 10km/h on 3% incline.Come back in about 3 hours. If he hasn't had a heart attack you should be able to find a vein to stick a needle in. Either way, problem solved.
Every time I read about jerks like this I think about a line from Charlie Daniels song "Simple Man"."As far as I'm concerned their ain't no excuse for all the rapin and the killin and the child abuse,but I've got a way to put an end to all that fast..Just take them rascals out in the swampPut them on their knees and tie them to a stump,let the rattlers and the bugs and the alligators do the rest!"
To all the people who cite the expense of execution as a reason to keep these bottom feeders alive rather than execute them I would point to this article as a rebuttal. Imagine: 3 hots and a cot every day for 22 years along with all his meds and doctor care. Did anybody know that when a scumbag like this goes to prison that not only do we pay his medical bills but he also goes to the very top of donor lists (if he needs an organ transplant) because he is a ward of the state! Immediate execution would save the taxpayers a whole lot of money. And might free up some organs that could be used to save actual human beings.
