Isn't pretty much everything illegal? (details inside)

I was in a muni court today and saw the definition of illegal taped to the computer at each workstation so that the public could see it. I looked it up when I got back and found that matched word for word the definition found in the Merriam-Webster dictionary.

to whit – ILLEGAL: not according to or authorized by law

The Free Dictionary says – ILLEGAL: adjective actionable, ... not according to law, not allowed, not approved, not authorized by law,....”

So to my way of thinking, if it is not specifically approved or authorized by law then it is, by definition (these two anyway), Illegal . Who knew we were all criminals.

Do you agree?
