Just tell them you're Archangel and you don't take no crap from nobody.
In all seriousness though, I can't say I know if OC is legal in those areas, but I do know that being calm, polite and respectful when dealing with LE will go a long way. Don't give in to everything they say, but it is possible to politely refuse. Also, smiling and saying "Yes, sir" and "No, sir" generally help.
Not saying he won't give you a hard time anyway. Some LEOs just don't like OC, same as anyone else. But it's less likely to escalate if you stay calm and respectful.
