I guess it's not enough for Democrats to tell their local police officers they can't assist with the enforcement of federal law. Now Democrat mayors feel the need to actually warn criminals that federal law enforcement is coming to get them, so they'll have a chance to get away.
Astonishing.
Oakland Mayor Libby Schaaf did just that in recent days, giving illegal aliens in her city a heads-up that an ICE rade was probably coming. The illegals made good use of the warning. While the feds were able to nab around 150 people - many of whom had been identified as public safety threats - more than 800 remaining public safety threats remain at large thanks to Mayor Schaaf.
