Factual error: Any time FBI agents enter Mexico, they are always armed. Mexican law prohibits U.S. Agents from bringing weapons into Mexico.
Factual error: The container for the dangerous biological material is marked "Biohazard Level 5." There is no level 5. According to CDC regulations Biohazardous materials are rated 1 through 4. Based on the description of the material in the episode, it would be required to be stored in a laboratory rated at Biosafety Level (BSL) 4. All BSL 4 labs require personnel to wear a fully enclosed, pressurized suit when inside the lab. (00:01:05)
Factual error: Lisbon is sending Van Pelt to El Oro State Forest. Van Pelt says, "El Oro State Forest, that's east of Lake Tahoe, right?" Lisbon says, "Yeah." East of Lake Tahoe is Nevada, not California. (00:01:17)
Factual error: When Jane is changing the tire on his Citroen DS 20 he uses a car-jack, but because of that car's hydropneumatic suspension you don't need one. (00:00:19)
Suggested correction: Good one! The DS 20 is a fantastic car and you CAN use the high-lift suspension to lift the car up to change the tire, but you still need the jack stand - supplied in the Citroen kit - to keep the tires off the ground for changing. Most DS owners find it much easier to just use a regular jack.
