Jail time is a deterrent on U.S. border
But in an effort to slow the revolving door of job-seeking immigrants willing to test high-tech sensors, bike patrols, and fences that guard the American boundary here, border patrol agents have initiated a tough zero-tolerance policy along this 12-mile zone that stretches west from El Paso, Texas.
Anyone caught crossing illegally, agents say, will be arrested and prosecuted, whether it's their first or 50th try. If they attempt to come back within five years, they face a felony charge. SARA MILLER LLANA for the Christian Science Monitor.
