Los Angeles Police Department officials say four officers scheduled to attend a conference and training session in Tucson next month will not go, sparking anger among police union leaders.

The trip to the annual Airborne Law Enforcement Association conference was thrown into question last month after the Los Angeles City Council voted to suspend most travel to Arizona as part of its protest of that state's law dealing with illegal immigration.

Two councilmembers sought an exception but that vote will now be tabled.

Paul Weber, head of the Police Protective League, calls it a mistake to sacrifice public safety for politics.

Arizona's new law makes it a crime to lack immigration papers and requires police to determine the status of people they suspect are in the country illegally.
