Because they're going to Texas:

Chris Simcox, the leader of the controversial Arizona group that is attempting to prevent the entry of illegal immigrants from Mexico, says he is considering October for the beginning of patrols along the Rio Grande in South Texas. Other patrols are being considered for New Mexico and California.

But Simcox says there are serious logistical problems for patrols in Texas. Most of the land along the Texas border is privately owned, and some of it is urbanized, unlike the open land the group monitored in Arizona.

And the same reports of drug violence that have scared some tourists away from the South Texas region have become a concern for the Minutemen.

"The Texas border is pretty dangerous right now," Simcox said. That won't scare the Arizona-based citizen patrols away, he said, but it does mean they will be more careful in planning their operations, which might even include efforts to disrupt the flow of drugs.

"Security becomes a serious issue because we are going to be annoying a lot of people," including leaders of the drug cartels, Simcox said.

That is the truth. Depending on which part of the Texas-Mexico border they plan to patrol, the Minutemen could run into anything from murderous death cultists (in the Brownsville-Matamoros area) to drug runners to terrorists--along with the fruit pickers and others who cross illegally for work and whatnot. Whether the Bush administration ever figures it out or not, the Mexican border is one gigantic security hole that drains the US of money while skewing all of our crime stats for the worse.
