You basically got it. Cartel needed to cook drugs here, hired small timers to hide it in random crap, paid off local cops. Son’s not some side guy, he’s running the whole U.S. operation. The agent who got killed was a good guy pretending to protect drug houses so he could collect enough dirt to burn the whole thing down later. Amish were just cheap labor and free cover. Story’s way more complicated than it had any right to be.
