Factual error: The police "clone" the cargo dock's computer, as though it were a cell phone, so that they can watch all the cargo traffic and see when containers disappear. In reality, to "clone" a computer would simply make an exact copy of that computer's hard drive at a specific point in time. In order to see what is happening on a specific computer in real time, it is necessary to install some sort of spyware on the target machine.
Other mistake: Season 4, episode 10: When Chris and Snoop go to kill Bug's dad, they have their high powered nail gun once again, even after previously throwing it in the marsh with the guns. Bought a new one? Not likely as the reason for throwing it away in the first place was because the cop saw it. Buying an identical one would defeat the purpose of ditching it.
