There are already laws on the books to deport criminals which occurred through out Obama's presidency. He deported far more than Bush or others ever did. This happened with cooperation of sanctuary cities. What sanctuary cities say they will not do is the job of ICE or other federal orgs. Please realize that if police are seen as immigration enforcement, this will drive people to fear police more than they already do and all crime will go up as it goes less reported. This is why those who live in those cities like me understand its better and safer to cm declare the sanctuary status. Congress needs to do its job and work on bipartisan immigration reform. Tearing apart families and deporting people who have lived their lives here peacefully and productively helps no one.
