Cleaning up illegal crews

Christian Science Monitor: The nation's largest employer, Wal-Mart, was raided last Thursday by federal agents on charges that its cleaning contractors were using illegal immigrants as janitors.
And indeed the predawn raid snatched more than 250 illegal immigrants at more than 60 Wal-Mart stores, while company executives are still being probed for possible prior knowledge of the hiring.
This dramatic enforcement of U.S. immigration laws against the world's largest retailer sends a powerful message to Congress, President Bush, and all those companies who prefer not to check the legal status of workers: If flag-waving Wal-Mart is getting away with this, do the nation's immigration laws mean anything in the vital task of stopping terrorists from sneaking into the United States? Mr. Bush needs to resume his pre-9/11 efforts with Mexico and Congress to end the massive flow of illegal aliens across the border so the United States can keep better track of who's in this country legally.
If giant Wal-Mart has been using illegal workers at below minimum wage as one way to drive hometown retailers and other competitors out of business, it shows just how pervasive and insidious this generally flagrant violation of immigration laws is.
