I guess my joke didn't come across. The Constitution already has the words "no ex post facto law shall be passed" in it (my joke is that all that work going back to try to add it would be wasted) right after the words that congress can't just declare someone guilty of a crime without a trial. Just Google "no ex post facto shall be passed."
