From this:

A long-standing order designed to restrict Los Angeles police from enforcing immigration laws does not bar officers from pursuing deported felons who have re-entered the country, Assistant Police Chief George Gascon told the Police Commission on Tuesday.

The interpretation of Special Order 40 - the 27-year-old policy that prohibits officers from arresting people for illegally entering the country and from investigating a person's immigration status - comes as Los Angeles Police Department leaders get ready to finalize a department directive on how officers should interpret the order's restrictions.

"We deal with violent felons who are wanted, regardless of what their immigration status is," Gascon told the new Police Commission. "We have always acted upon information regarding this very specific population."

The article then contains quotes from "liberal" activists and mentions that this "clarification" was prompted by Heather MacDonald's articles. What exactly this "clarification" means and what exactly the police are actually doing is a bit unclear; perhaps "Jack Dunphy" will weigh in at NRO.
