If you have never worked around inmates, LWOP seems like a good alternative. In my humble opinion, it is not.
A lot(not all), inmates that have been sentenced to very long prison terms, seem to have the same mind-set. If you catch one at a minor or sometimes major, rule infraction it seems like more often than not, what comes out of their mouth, is, "What are you gonna do, put me in jail? I'm already in jail. Do what ya gotta do po-leece, but you still gotta feed me 3 meals a day, bring me clean clothes, etc, etc".
If you take a bunch of these guys, that will NEVER get out, what incentive do they have to stay out of trouble? Kill an Officer? "What are you gonna do, etc., etc". Kill an inmate? Same thing, only the State is in trouble for not protecting inmates and is likely to be sued for millions, by the family of the deceased. Technically, a LWOP inmate could kill multiple people over the years and STILL be a LWOP inmate. Think of the medical care for an aging LWOP population. It would be staggering.
I spent 25 years watching these thieves, er, uh, inmates and I've seen how they respond. Death penalty or LWOP? Death penalty, but DR inmate shouldn't be on the row, for more than 3 years.
All you good Folks in the European Union, your God loves you but I don't really think your opinions about our system means just a whole lot. You know what they say about opinions, huh?
