"Sanctuary cities" are simply jurisdictions that follow first the US Constitution in their application of law enforcement. Take note that the "sanctuary cities" are the ones that are safest because the people know their individual rights under the Constitution will be protected. Not too long ago, tea partiers were ranting about the federal "jack-booted thugs" imposing their will on citizens. Now they are backing laws like this to make local authorities act as the same jack-booted thugs on behalf of the federal immigration authorities. Furthermore, how does cutting any grant funding for local law enforcement improve safety for local residents in ANY way? This is a despicable law.
