What law? Code sec/ statute etc?

Not trying to come across as a jerk, but too often people think they know something but never look it up to be sure what they believe is actually true and go about their business blindly assuming their uncorroborated belief is valid.

Especially when it comes to laws.

I research legalities every day at work, I'm quite adept at it - but I'm well aware of the truth to the old saying "You don't know what you don't know" and I just because I haven't found it doesn't mean it doesn't exist. But anecdotes are not going to answer my question.
