Retroactively Undone and Repealed
When cops get caught planting evidence, lying under oath, etc., sometimes other pending or past cases which relied upon the testimony of that cop also get thrown out. Because hey, once the guy is a proven crook and liar, how can it be okay for anyone to be locked up based on what that slimeball claimed happened? (That happens less often than it should, but it does happen.)
Now suppose that that principle was applied to politicians. (I can dream, can’t I?) If every time a politician was caught lying, cheating, breaking the law, taking bribes, covering stuff up, etc., then everything he ever helped to “legislate” was retroactively undone and repealed, where would we be today?
Simple. We would be in anarchy (literally)!
