the patriot act says the bill of rights is null and void Original Article Jun 30, 11:31 AM EDT Border Patrol traffic stops near Santa Fe alarm some SANTA FE (AP) -- U.S. Border Patrol agents are conducting traffic stops farther north to find smugglers of illegal immigrants, a move that alarms immigrant advocates. Border Patrol agents have been operating near Santa Fe and elsewhere in northern New Mexico this week to gauge the extent of human smuggling in areas farther from the Mexican border, Border Patrol spokesman Doug Mosier said. Immigrant-rights advocates, however, said the patrols are causing worry among Santa Fe-area immigrants. Marcela Diaz, director of the immigrant-rights group Somos un Pueblo Unido, said her office received calls all day Tuesday and Wednesday about agents stopping motorists on Interstate 25. Diaz said the agents' presence along the main route between Santa Fe and Albuquerque has had a chilling effect on some immigrants and their families. "When people see border-patrol agents, especially when they are looking out, they get nervous and don't want to go to work and leave the house," Diaz said. Mosier said the federal agency began an "enforcement action" based out of Albuquerque earlier this week, but he refused to supply details of the operation. "I don't want smugglers to know anything about our operation and our resources," he said. Mosier said agents were looking for anything that falls "under the umbrella of homeland security," which could include human, drug or weapons smuggling. The operation is part of a nationwide effort, he said, and is unrelated to any terrorist threat or Independence Day.
