There are cases of people getting released after DECADES. Your life is pretty much ruined then.
Well, there's a huge difference between life being ruined and life being over. One has a chance for getting some semblance of a life back. I can't see how death would be preferable even if the goal is to reduce both.
Death candidates wait several decades as well for their execution.
That's narrowing. I think the average is about 10 years now, but it's going closer to five. Habeas cases are virtually impossible to succeed these days and you really only get one shot at that plus the direct appeal (if you assume two for both that's four years before they can start planning your execution).
Florida just passed a bill to speed up the death penalty process
. When pointed out that the delay allows innocent individuals to have a chance to be exonerated, Republican Senator Rob Bradley responded with, "This is not about guilt or innocence, it's about timely justice." In other words, it doesn't matter whether the person executed is innocent or not, society needs to see someone executed quickly for justice to be served.
