BARF

Acronym for "Border Alien Robbery Force" which was a police commando team sent to patrol the snake-infested no-man's-land south of San Diego, not to apprehend the thousands of illegal aliens slipping into the U.S., but to stop the ruthless bandits who preyed on them nightly--relentlessly robbing, raping and murdering defenseless men, women and children. The task force plan was simple. They would disguise themselves as illegal aliens. They would confront the murderous shadows of the night. Yet each time they walked into the violent blackness along the border, they came closer to another boundary line--a fragile line within each man. and crossing it meant destroying their sanity and their lives.

This real life saga is depicted in the book "Lines And Shadows" by Joseph Wambaugh.

Politicians stopped funding BARF because they could not exploit it for votes and they considered their mission a job of Border Patrol.
