There are over ten millions laws in the United States. Many of the are contradictory. I know this first hand because I was an ovder the road truck driver for almos three decades. Truckers break he law every day. They have no choice. If they do one thing it breaks a law of they DON"T do that thing they break another law. If they do nothing at all and stay in bed , you guessed it......they broke a law.
It's the same way other places too...
there's a couple of laws in place about almost everything. It's illegal if you do it. It's illegal if you don't. They're generally not enforced.
Unless you annoy someone in power.
