So you have no problem with the police and their refusal to cooperate with the feds. If they were carrying out an illegal order of the mayor or council don't they share some of the blame. To be sure the police are generally and usually correctly seen as the heros and the "liberal" elected officials as the bad guys by most conservatives...well if so why didn't they pull a Kim Davis? See what I mean by it not being so cut and dried in the sanctuary cities situation?
It is instructive that you point out the "Democratic" mayor needs to be prosecuted for not following the law. Now be honest, would you call for the same action against a Republican Governor who refused to order state officials to abide by the gay marriage ruling?
