> If a school tells you that you can't do what's right by your child because "it's the law," ask for the citation of the law. If it's really a law, there is a citation, and the law can be looked up. In the United States, under its Anglo-American system of law, the default assumption is individual liberty (and parents rather than schools acting in the interests of minor children), so make sure to check the specific law before believing your freedom is restricted by the law in the manner the school official claims.

Unfortunately they're likely to mumble some semi-related law and then call the police.
