This is WEEKEND EDITION from NPR News. I'm Scott Simon. Last month, U.S. Immigration and Customs Enforcement made a significant policy change. They increased the number of agents responsible for finding and deporting illegal immigrants with criminal records by nearly 25 percent. Now, the agency says it wants to remove offenders who pose the greatest threat to public safety or national security.
For the most part, we don't hear novel arguments in favor or against the controversial issue of immigration. Mayor Michael Bloomberg has been one of the few to take a different view. Last year, he advocated opening the door to new immigrants if they all moved to Detroit.
