I doubt it costs more to kill someone in a day, than it does to keep them for life in prison. Resources are low. And that Illnois argument is just a fault on that town/state, the general "death row" system is flawless. It would be illegal to put someone to death if they are innocent, and I'm pretty sure if you're on death row they have SOLID evidence. It's not like the old days, back then it was flawed, but in the modern days I can't see anything wrong with it.
