That's absurd. The legal test is whether a reasonable person could have known that they were an accomplice to a crime.

The article makes it clear that this man knew he was building these for cartels, and tried to weasel his way out by claiming he'd never seen drugs with his own eyes, but had seen almost a million in cash from some very shady guys.

This would be like running a "Taxi service" that catered to Balaclava wearing gentleman exiting a bank, claiming that you had no idea you were helping with a robbery. Perhaps they're just really ugly businessmen in a hurry? Would that mean nobody could drive a Taxi anymore? Of course not.
