There are a lot of "laws on the books" simply because there's no mechanism to go back and remove old laws. It doesn't mean they are relevant, enforced, or even still legal. Many laws technically stay on the books even after a court rules them unenforceable. It means nothing.
It's like having a 30 year old comment in a Windows driver about a variable no one uses anymore - no one cares and it doesn't reflect anything today.
Also, ONE stupid incident with ONE stupid prosecutor does not reflect society.
