How is it your 10 year old understands the concept of "Rule of Law" vs "Rule by law" and you do not? No, the police can not make up the laws on the spot. Throwing anything at a police officer is illegal. Threats to burn down the school should be investigated. Instead of teaching your child that the justice system is oppressive, perhaps teach him that his words and his actions have consequences, and if he says something that could threaten the health and well being of others, he will be treated as a threat to society. Yes, intervening in an arrest is illegal. And if you do not take the summons he hands you for breaking the law, you will end up in jail. No, cops can not handle the problem however they want, and it is quite inconceivable that any adult would believe this

You seem to think that laws, and their enforcement, is something you can opt out of if you do not agree with them, and that if society disagrees with you, then you are a victim of oppression.

Hopefully, for your child's sake, if a police officer tells him to put his hands up, he will. The fact that you never would is just plain irresponsible, and you may well end up dead as a result of your holding firm to your dangerously irrelevant ideas of what you think you have a right to.

If you want to keep your child safe, teach him that breaking the law has consequences, and that he should, whenever possible, not break the law.
