TUCSON -- On an isolated ranch 10 miles from the Mexican border in southern Arizona, Tangye Beckham worries about what the night will bring. That's usually when her family's 100-acre ranch begins to crawl with drug and immigrant traffickers from Mexico heading north into the United States.

Dever has lost four friends -- three police officers and a rancher -- to cartel violence, and insists Mexican traffickers crossing into his county are well-armed and much more aggressive now than they were just a few years ago. "We're getting overrun from the south, because the federal government isn't doing its job," he said.
