Fleiur implied that we just execute them immediately after they've been convicted; completely bypassing the appeals process. True, they did later amend with this post:
But it doesn't make any sense as a clarification, because by suggesting the bullets it implies that we should execute them on the spot. The method of execution isn't the issue in terms of cost; it's the appeals process, and we cannot do away with that in any way.
Look, I'm against the death penalty period; for reasons I previously laid out. Killing is wrong, they could be innocent, and it's too expensive. That said, I understand why others are in favor of it, and I wouldn't argue that using it on pedophiles and rapists is wanton; what's wanton is doing so without giving them every chance to prove their innocence, above and beyond a single trial, and it is this which makes the death penalty so much more expensive than just locking them away for life.
