If you’re a government official unwilling to enforce the laws on the books of course their must be sanctions to your city/town. Laws that you don’t believe are just must be challenged in the court system and if you neglect to follow them well just like a private citizen there are consequences. Therefore “sanctuary cities” must face penalties for there to be justice for all. As a private citizen I might violate the speed limit but I know if I’m caught I will receive a penalty therefore I wouldn’t announce to the police force where and when I would be speeding. These cities are and have been announcing when and where they are breaking the law and therein turn their is no choice sanctuary cities must be sanctioned.
