CBS News on ATF letting guns go to Mexico
Video here. Complete with an agent, still on the job, who talks about it. (That takes serious cojones -- I mean, he has to go into the office tomorrow, with the same supervisor that he's talking about, who now regard him as a "snitch," to be ruined).
They're talking thousands of guns that only got to Mexico because ATF supervisors said let them go. Superiors telling agents who complained that this is "fun" and they can go out and find a different job if they don't like it.
