I do not have personal experience with a death penalty case, but I'll share my thoughts like some others have.
Previously, I did believe in the death penalty, but after much thought I have changed my mind. I have read a few books where the innocent have been killed by execution. I think that execution and abortion should not be allowed. I view them the same, as government sponsored killing. >
However, with that being said, in my view, prisoners who would have been on death row should serve a lifetime of hard labor. Everyday filled with hard labor and anything they earn goes to the family of the victim. No education opportunities, no TV, no lounging around. Work, eat, sleep - for the rest of his/her natural lifetime.
