The federal government has posted signs along a major interstate highway in Arizona, more than 100 miles north of the U.S.-Mexico border, warning travelers the area is unsafe because of drug and alien smugglers, and a local sheriff says Mexican drug cartels now control some parts of the state.

The signs were posted by the Bureau of Land Management (BLM) along a 60-mile stretch of Interstate 8 between Casa Grande and Gila Bend, a major east-west corridor linking Tucson and Phoenix with San Diego. They warn travelers that they are entering an “active drug and human smuggling area” and they may encounter “armed criminals and smuggling vehicles traveling at high rates of speed.” Beginning less than 50 miles south of Phoenix, the signs encourage travelers to “use public lands north of Interstate 8″ and to call 911 if they “see suspicious activity.” “Mexican drug cartels literally do control parts of Arizona,” he said. “They literally have scouts on the high points in the mountains and in the hills and they literally control movement. They have radios, they have optics, they have night-vision goggles as good as anything law enforcement has.

“This is going on here in Arizona,” he said. “This is 70 to 80 miles from the border – 30 miles from the fifth-largest city in the United States.”

He said he asked the Obama administration for 3,000 National Guard soldiers to patrol the border, but what he got were 15 signs.

But like the man said…the borders are quite secure.
