Factual error: While attempting to capture one suspect the police go to the island Curacao. The island is one of the three "ABC" Dutch Mediterranean Islands - Aruba, Bonaire, and Curacao. The map incorrectly labels Aruba as Curacao. (The islands left to right are actually Aruba, Curacao, Bonaire).
Factual error: The Columbia paramilitary is seen throughout the 2nd season carrying M4's. The M4 configuration of the M16 was not available during the period Norcos took place. In one seen in fact an M4 has an EOTech optic mounted on it...backwards. Not only is the optic backwards, EOTech was not founded until the late 90's or early 2000's.
