Proof please, let's not just bring these 'facts' to air without supporting evidence.
I haven't seen other people citing sources, but as you insist, I've tried to dig up the articles I was thinking of. Mostly they come from things I read in print editions of
Christianity Today. Which, as regards issues of opinions and beliefs among Christians, seems reasonably reliable to me.
A bit dated here, but regarding declining support for capital punishment:
http://www.christianitytoday.com/ct/2008/march/6.20.htmlI'm trying to hunt for the info about opinions within Christian groups. Problem is it wasn't in an article about the death penalty, but was in a section of the print magazine where they cover, in brief, lots of odds and ends. So finding that might take me a while.
And regarding the appeals process... really, I don't think I need to cite sources on that. It's common knowledge. You can look that up for yourself very easily.
