A simple public hanging would be sufficient. As usual the mob and its ignorant “leadership” have overly complicated simple justice turning it into an emotional high drama complete with a rending of garments and scratching of the face.
Of course, you’d have the left suddenly digging up the “fundamentalist Christian” aspect of a hanging, since the Bible says that whomever is hanged is cursed by God (Deuteronomy 21:23 and Galatians 3:13).
And if you wanted to go you would have to wear hairy garments and that would be uncomfortable.
