Terry was an ICE Agent right? So there is a good chance he did not even know of this crazy scam.
Brian Terry was a CBP agent.
One of the least corrupted Federal agencies.
ICS, ATF, DEA, FBI and most if not all of the alphabet agencies have been politically corrupted.A few individual agents of each agency have been bribed, but it a damned few.
CBP seems to be the exception. Maybe because they are on the front lines and see the shit every day.
As for this crime my guess is the odds of Agent Terry knowing about it were probably 100 to 1 or more.
