If there were a way to be absolutely sure about someone's guilt.
If there were a way to ensure those executed died near-instantly and without unreasonable amounts pain.
I would support the death penalty for those convicted of violent and/or cold-blooded murder and/or rape.
It's really a case-by-case thing.
Sometimes I think we're alone. Sometimes I think we're not. In either case, the thought is staggering. ~ R. Buckminster Fuller
However because of the ridiculousness of our current judicial appeal process, most (all?) DP inmates have just as many years to escape and/or kill other inmates or prison employees as most 'lifers.'
This is what happens when we allow our emotions to run away with us. The death penalty is taking out the trash. It's not vengeance.
