Certainly, but it appeared to me that the post claiming that what the police did was wrong was indeed operating from the framework that a police department not subjecting itself to the laws it upheld was wrong in the deontological sense. Hence the claim "Yes, obviously. At the very least, they very obviously broke a law. They should file charges against themselves." That's not a utilitarian statement - it operates from the framework that the action itself regardless of circumstances was wrong, and while a jury or judge could exonerate them, they still have the duty to place themselves under arrest.
