The DEA’s snitch had gotten out of Cartel favor by losing a load —it appeared he might lose info access. But if their snitch were able to steal a rival incoming load, then he’d be straight again with the Cartelistas and the DEA’s Intel might turn out OK.
So the DEA and Fibbers spilled the beans on the impending load to their criminal snitch, and at the rip Terry was killed.
If instead of a US cop dying, say, 20 poor Mexicans or mere US citizens were killed, do you REALLY think we’ ever had heard any of this...?
WE DO NOT MATTER TO THEM AND NEITHER DO THEIR OATHS.
We are lucky we ever heard about Brian Terry or Jaime Zapata. Serious efforts were made to keep those stories quiet.
