I'm also a proponent of the death penalty, but only if used as a deterrent. Should be done in a public forum, shown on tv, and set up for the maximum number of people to attend and watch. I would also consider making it mandatory to be shown in high schools, and for high school student attendance if the execution is within the same city or town.
As for sitting on death row, the appeal process should be limited to one year. With both State and any Federal constitutional issues being decided at the same time, with opinions from both courts being decided and published within that one year period. I would also do away with any immuniites for police, prosecutors and judges.
One year, huh?
