No idea about the situation in the US, where there are constitutional rules about this stuff, but here in my jurisdiction in Australia, they fairly recently passed laws making it illegal to resist arrest even if it turns out the arrest was unlawful. The idea being that the most appropriate place for determining whether an arrest was lawful is in the courts afterwards, as opposed to risking escalation of force at the scene of the arrest, and thus it'll improve safety, or something. I'm not quite sure I buy it, and I suspect our local bar associations may have disagreed too. Though situations of unlawful arrest are fairly rare all things considered, I guess.
