Idiot statement. You question laws in a legitimate way not decide which ones you wish to obey. Don't wish to obey the laws? Move out of our society.
It's not an idiot statement at all. You originally suggested that there was a moral obligation to report people who break laws whatsoever; I disagree. I don't think there's a moral obligation to report people breaking the law if e.g. the is immoral. We can all think of examples of immoral laws - section 28 (the "gay propaganda" law) was an example of one IMO.
I notice you are now shifting your argument to talk about a requirement to obey the law. That's a quite different thing from your earlier point, which was that people show report others who do not obey laws. And again, I don't think there is a moral obligation to obey laws if they're immoral. To take a bleeding obvious example to avoid any accusations of subtlety, Nazi racial purity laws were immoral, and I don't think anyone was under a moral obligation to obey them.
I think you're confusing law and morals, and obeying a law and reporting others' refusal to obey a law.
