The Texas Standard wanted to find out what the Border Patrol is authorized to do and what people's rights are. They interviewed a lawyer who works with the Texas branch of the ACLU to find out. She (the lawyer) said:
- The Border Patrol can legally stop someone for no particular reason (they don't need to have a probable cause).
- The Border Patrol can ask questions to find out whether a person is authorized to be in the United States.
The lawyer recommended that people cooperate with the Border Patrol and, if they believe their rights are violated, enter a complaint later.
Since this was only a five-minute segment, I felt that it left a lot of questions unanswered, but at least it explained that much about how the U.S. Government works.
