The farmer said a federal law enforcement agent told him to buy a bulletproof vest to use while working in his fields. Whenever he goes out to survey his agricultural operations, he always tells his office where he is headed, and he has purchased a high-powered rifle…

The Obama administration and many local officials have said the U.S.-Mexican border is safer than ever and that reports of violence on the American side are wildly exaggerated.

Veterinarian and rancher Mike Vickers heads the Texas Border Volunteers, a group of about 300 landowners and supporters who work closely with law enforcement officials to track drug and immigrant smugglers entering the U.S. from Mexico and crossing private land. His primary concern, he said, is the safety of farmers and ranchers who have been confronted by armed traffickers.

“A lot of them have been threatened not to call the Border Patrol or law enforcement if they see smuggling going on their property, otherwise they’ll be killed or their family members may be killed,” he said.
