Its just that most cities don't want to spend their resources and their money rounding up, processing and detaining illegals simply because the Federal authorities don't have the people to find them, arrest them or the facilities to lock them up. If a local illegal gets busted for drunk driving or beating up his wife he gets processed in the system exactly the same way as if he were a citizen. It is not the job of the local courts and jails to round up people who break Federal laws or turn them over to the immigration authorities, and certainly not to hold them until ICE finds the time to come pick them up.

If ICE wants to arrest somebody in my town, nobody here is going to stop them (I live in SE Florida). But the local authorities have better things to do with their law enforcement dollars, personnel and facilities than help Donald Trump score points with his knuckle dragging Deplorables.

"Sanctuary cities" is just another Trump lie, designed to inflame the redneck vote and racist Right and turn them against the more liberal governments and voters in the cities. What ICE really wants is for the cities to drop everything else they're doing and rush to help the immigration authorities do their dirty work. When they refuse, they call them "sanctuary cities", as if they were harboring serial rapists and axe murderers.

If the GOP was really serious about illegal immigration they would just start enforcing the laws about hiring undocumented workers by fining and jailing some of the Republican fat-cat businessmen who are harvesting all that foreign cheap labor. That's why the illegals are here, because Republicans are getting rich by hiring them. Can't you see? These people are here because OUR BOSS invited them here.

But nooooooooo....When THAT bill was introduced in Congress, the GOP shut it down tout de suite.
