More than 400 anti-immigration activists gathered in Las Vegas over Memorial Day weekend to bemoan President Bush's failure to close the borders. One described the United States as a nation at war “every time a Mexican flag is planted on American soil.” They celebrated their most recent success: a “border watch” in Arizona by fewer than 400 Minutemen vigilantes that had generated millions of dollars of free advertising. In the aftermath, Minutemen shops opened in Texas, Colorado, and Tennessee.
