When the laws are completely in every way unequally enforced there becomes a good motivation to ignore them in general.
“Our government... teaches the whole people by its example. If the government becomes the lawbreaker, it breeds contempt for law; it invites every man to become a law unto himself; it invites anarchy.”
Louis D. Brandeis
That could be said of Trump and the “show me a man and I’ll show you a crime” mentality.
