The Mexican staging area for illegal aliens that New Mexico Gov. Bill Richardson demanded this week be bulldozed is among hundreds of similar sites along the border sponsored and maintained by the Mexican government.
Many of the sites are marked with blue flags and pennants to signal that water is available. Others, such as the Las Chepas site that Mr. Richardson denounced, are a collection of old, mostly abandoned buildings or ranch houses where illegals gather for water and other supplies — sometimes bartering with smugglers, or “coyotes,” for passage north.
Las Chepas, law-enforcement authorities said, also is a center for drug smugglers looking to move marijuana and cocaine into the United States.
Rafael Laveaga, spokesman for the Mexican Embassy in Washington, yesterday said his government “has a duty and obligation by law to protect Mexican citizens at home and abroad.”
He said record high temperatures in the desert areas south of New Mexico and Arizona this year had resulted in the death of many illegal aliens.
“We try to spread the word on the dangerous conditions these people will face in the desert, along with reports of historically high temperatures,” he said. “What we are doing is part of an effort to prevent those deaths.”
