> Well, US has a problem with obscenities for instance, which are erased from court records, even if everyone in attendance is an adult and should be able to handle some cuss words.

This is not a universal practice. In fact, I'm inclined to say it's rather rare.

A case that immediately comes to mind is Cohen v. California. It concluded that governments can't ban the use of the word "fuck" in public. The word is not censored in the opinion.
