Who cares if his injection might hurt a few minutes. I would say this poor child suffered much pain...IMHO so should Broom. I like the idea of hanging him. Hang him in the yard so all the inmates can see it. Put it on TV so everyone can see it too.
Feed him to the ants while he is tied down to an ant hill and covered in honey 60 miles from the nearest city and he can scream all he want, which I hope would be for days.
