Arrest, even if you're not charged ultimately there's a lot of power in being able to just initiate an arrest suddenly you're resisting arrest if you aren't cowed immediately and even if the original charge is bogus you've got the cops get out of liability free card of slapping on a resisting charge. And even if they don't pull that legal judo move you're still stuck in the system for a while and that's majorly disruptive to your livelihood even if you don't ultimately get charged with anything and get released asap.
