Does it really make any sense to tell people to stop doing what they really want to do? And then punish them for doing what they were doing before it became illegal?

Why isn't it illegal to pass a stupid law that serves no real purpose? Why isn't it illegal to pass a law that punishes people for something that is a manufactured offense?

And why isn't it illegal to punish people by putting them in offensive circumstances that are worse than the supposedly illegal offense that they committed?
Prisons are nasty disgusting places where society gets to shove the people they don't know how to deal with any other way. But what's worse are the nasty disgusting people who come out of those prisons more nasty and disgusting than they were before. And what's the worstest is the folks who don't get caught or don't get incarcerated, who are wandering around doing just what they please.

Why isn't it illegal for regular folks to just stand around and let the mean people do what they please on the grounds that since they are nice people, they don't want to get involved.
