It's not a tough one to me - no death penalty, regardless of the crime. What good would it ACTUALLY do? It wouldn't bring anyone back and - should you think this way - a life of solitary confinement would arguably be more of a punishment that instant death and being put out of your misery.
I very rarely read books, but the last one I DID read – The Sun Does Shine, by Anthony Ray Hinton – reinforced my views about the death penalty and how there's still a LONG way to go to overcome 'the system' and right the wrongs of miscarriages of justice.
Let's hope Mr Sullivan is looked after...
Quite possibly lawyers (on both sides) dragging their heels and making a fortune. Although I'm sure there is a LOT of paperwork and bureaucracy involved to make sure they are 100% certain.
