There is a military leadership axiom that says: "Never give an order you know won't be obeyed". The more laws enacted because someone cries "DO SOMETHING" about a particular pet peeve, the less respect people have for the law. Speed limits are one good example; income tax law is another. When the law is so complex and voluminous that only lawyers understand it (and that only the parts they study as a specialty) and everyone becomes a criminal in one way or another, people find it easier to disregard the laws they disagree with. It's a slippery slope that's brought us to the brink of governmental tyranny at all levels and it will be hard to turn the tyranny back. I can't think of a single new law (as opposed to a law repealing another law) that we need in this country or that would be good for us.
I don't know about that. The regulation about not being on the phone while driving on post is a stupid one, but many people follow it because it's not worth an Article 15.
