Personally, I'd like to see more of the condemned actually DIE!
20-30+ years on death row is a joke.
Some time after PC and the web were invented, I read a short Sci-Fi story that addressed this problem.
In the future the story went those condemned to die were placed in a special cell. Everyone had to pay a small fee to participate in voting.
While the condemned was eating their last meal the world was voting on was he to live or die. If the vote came in he should live he was taken back to his or her cell and given a life sentence.
If the vote came in for death, the prisoner was vaporized, instantly, had no idea of it coming and there was no pain or worry, he/she enjoying their last meal just went POOF.
Oh the money that would be made from the world for those that guessed the outcome.
If this became a fact in the future with all the facts laid out before hand, sort of like Court TV but the world became the jury.
No pain, no suffering, very civilized.
Now if this happens in your life time would you buy a $5.00 ticket to be able to vote ? The odds makers would clean up and fill a stadium full of voting machines at each seat with a wide screen projector, the bookies would be able to be on site and like the Dog tracks one if guessing correctly could claim their money on the spot.
Remember also that when there was a public hanging of a pick pocket the crowds came from miles around to watch. Many returned home to find someone in the crowd had pick pocked their time piece as they stood watching the hanging.
