As Drudge blasted yesterday, the INS raided several meat-packing plants across the country yesterday in an illegal immigrant search. The greatest impact was in Colorado. Employers not sanctioned. A reader from Colorado notes the timing  – Our Lady of Guadalupe. This article makes the connection and the reader adds:

Even in my mostly-white parish, a devotional talk
about Our Lady of Guadelupe connected the image of
Guadelupe to political movements, especially Cesar
Chavez.  I wonder how the enforcement agencies could
have been so ignorant to schedule their raid for a day
that would generate more than usual tension, political
opposition, and bad press.  One of those affected is
even named for the Virgin!
