I guess you haven't heard about what happened to Boob Barf after he lost his Congressional seat. He went off the deep end, started associating all sorts of liberal causes (even going to an Al Gore event to "raise awareness" of global warming) and did everything he could to trash conservative Republicans and overturn all the good thing he support in Congress like the Defense of Marriage act.
Today's Bob Barr has virtually NOTHING in common with the common sense conservative Bob Barr that served in Congress (I guess they both strongly support gun rights, that's about it). Bob Barr today IS sympathetic to cop-killers (not to mention terrorists), and is a paid ACLU consultant.
I’m for the death penalty, but I’m also for fair trials and compelling evidence. If we’re going to put someone to death, we ought to make certain that he committed the crime. This perp has offered to take a lie-detector test, but state officials refuse to let him. Also, certain witnesses have recanted their testimony. There is even a case where someone else is said to have admitted to the shooting.
