It is cheaper to let someone live the rest of their life in prison than to execute them.
I call BS. I will do the job for free. I will use my very own Glock .40 cal. a box of rounds is real cheap. So they don't have to pay a salary, they don't have to pay for the weaponry, all they have to pay is a box of rounds that will take care of 50 scum bag's. I don't mess around, 1 shot 1 kill. I would say it would be cheap to KILL'EM ALL.
