Last week, photos surfaced from Texas and Arizona showing Border Patrol processing centers overwhelmed as thousands of unaccompanied children from Central America continue to need shelter and resources. The photos show hundreds of children sleeping in crowded, chain linked cages. Agents have described the situation as a humanitarian crisis.

In response to the leaked images out of Arizona, Patrol Agent in Charge Leslie Lawson is cracking down on the use of personal technology by agents in the Nogales Border Patrol processing center.

"Due to the recent unauthorized use of a personally owned electronic device in the Nogales Processing Center, the use of such devices will be restricted to locations outside of detention areas," Lawson wrote in a June 6 memo to all employees at the Nogales station. "Effective immediately, the use of personally owned cellular phones, cameras, or recording devices in the Nogales Detention Facility and the Nogales Processing Center is strictly prohibited. All personnel working or visiting detention facilities at the Nogales Station will be required to turn off these electronic devices and store them in a locker other secure location prior to entering the detention area."

According to sources, agents have been threatened with firings if found to have leaked the photos to media.

"They are looking to fire any agents involved," one source said anonymously for fear of losing their job.

"Apparently they are so ticked over these photos that they are going to fire the person that leaked them," another source said.
