Yes. Don't say things that the public disagrees with. Don't question what you're told. That's the lesson.

Of course I think the Sandy Hook shooting was real, but if someone said it wasn't I'd just think they're an idiot - not a criminal that should be tried in any court.

He wasn't tried as a criminal. This was a civil case between private individuals, under defamation laws. Withholding evidence and perjury, however, are actual crimes.
