You too are confusing Criminal law with Civil law and being deliberately obtuse. Ignoring any civics class you ever took and what checks and balances are and how it works....Oh no, not from this day forth. From this day forth you just say, "are you shitting me, taking that car without paying for it is illegal? Man, why do they have them on the lots with big signs on them saying "try me" then? well, my bad" and you are free to go on to do something else you didn't "realize" was illegal.
Pretending that it is all the same when you know that it is not.
Anyway, in a Criminal case in almost every instance that is exactly what they do. They say, "I didn't do it, and if you find I did I will tell you some reason to give me less of a sentence."
