Sanctuary Cities ignore Federal law when they do not enforce the immigration policy set forth by congress. This is not a State right, the issue is ILLEGAL IMMIGRATION that may threaten the safety of our country. Our immigration policy is outdated and a politically correct hand grenade. The Nations policy regarding immigration should be addresses along side of the protection of our borders and the enforcement of the Nations laws. I can only think of one other law that has become optional and that one has nothing to do with national sovereignty, canibus consumption.
