Oh boy, I know the state of Nebraska will be happy to support these scumbag murders for the rest of their natural lives with food, a nice cell and plenty of love and special care...including paying for all their medical needs even if it's transsexual surgery. Good decision you dumb bastards.
Executions are staggeringly more expensive than life without parole is.
That's only because of the numerous amount of appeals they're allowed along with the cost of "humanely" executing the murderer.
We allow a lot of appeals because we don't want to execute innocent people incorrectly. Even given the current system, we still sometimes do.
