I have seen this story before and I do not think it is a current one.
It was posted on their website with today’s date, but you are correct, a search yields this.

It may be an old story but conditions have not changed. The article did not mention the region from Sasabe through Nogales to the Huachucas which in parts is worse than anything to be seen in the Tohono O’odham Indian rez. Even worse, hikers no longer feel free to roam the region around Pena Blanca Lake, or Ruby Mine or Sycamore Canyon, or parts of the Harshaw. The names mean nothing to most folks, but they were a small slice of Paradise in southern Arizona. As you can see from the article the abettors worry that the poor dears may have problems crossing the border. They place water jugs at strategic points. When the ranchers and Indians threaten to beat the hmmmm out of them the feds warn that any such action will result in jail time for the patriots, of sorry, miscreants. It’s a topsy-turvy world folks and the Mexican criminal element has actually found an ally in the Congress of the United States and the Bush administration. In case you didn’t know, the Border Patrol is so demoralized that most so-called agents don’t even bother to do their job. As for Customs people, they don’t even give a close look to those entering the US with purported US documentation. However, enter the country with two bottles of booze and you are in real trouble. The liquor monopoly, whose major ally is John McCain (and his beer-baron wife) has got them well trained.
You're right, we're now up to our hips in trash..Do you have the update story?
