New Orleans police officers will no longer enforce federal immigration laws without a warrant or a court order as part of its new bias-free immigration policy.The change has been in the works at the New Orleans Police Department and went into effect Sunday. Officials said the policy is intended to improve relations between immigrant communities and the police department.“This is an incredible step in transforming New Orleans into a more inclusive city for all residents,” said Councilwoman LaToya Cantrell, who authored the council’s "Welcoming Cities" resolution. “Chief (Michael) Harrison truly stepped up to get this new policy in effect, and none of this would have been possible without years of work from the council, the administration and our many immigrant support groups, including the Congress of Day Laborers, Puentes New Orleans and the Asian Chamber of Commerce.”Related: NOPD begins effort to build team of bilingual officers across police forceNOPD officials said the new policy means that unless there is a direct threat to public safety, officers will no longer enforce federal immigration laws without a warrant or a court order.
