There are several people on this thread who are determined hold their breath until the Truth goes away.

About the border agents, our geniuses in Congress pass the laws and make the rules. Most don't really want the illegals prevented from entering the country so they make the agent's job impossible to perform. Win-win for our certain members of Congress, Hell for the agents.

The agents are supposed to find people crossing the border and ask them politely to go back.

What Ramos and Compean found were advance agents of a Mexican drug cartel, a van with 734 pounds of drugs and armed suspects, one of which was ready to fire on them.

We don't need the exact details of this case to know that the agents were undertrained and were working under an intentionally vague game plan. Repeat what I said before: this was prosecutorial lynching.
