I taught my kids the rule of law and what's right and wrong or desirable are totally separate concepts. The law itself only tells you what's proscribed and potential penalties, all of which have to be analyzed in the light of how or who will actually bother to enforce it and the incentives of the various parties enforcing it.

Unfortunately the police come to public schools and try to do their brainwashing very early before you have the opportunity to even address it. So unless you address this issue at a very young age they likely won't question it again until near college age.

You should be careful to distinguish "rule of law" from the law itself.

Rule of law is merely the principle that laws should be applied equally to all. It shouldn't matter if you're rich or poor, man or woman, a member of the majority or minority race, famous or obscure, politically well-connected or not, etc. This is an inherently just principle, but it's also extremely difficult (impossible?) to live up to 100%.

On the other hand, you're correct that individual laws can be just or unjust, moral or immoral. We have plenty of historical examples of unjust laws (e.g., a recent and hopefully unquestionable example in living memory is segregation), and it's our duty to oppose them through voting, contacting representatives, protests, and perhaps even civil disobedience.
