Factual error: At the beginning of the episode, Patrick Swayze is looking at photos of two Iraq veterans who have been murdered. He identifies one as a Marine Lance Corporal and the other as an Army PFC, but both pictures show men in U.S. Army uniforms. A bit later, his partner, who is supposed to be a Marine vet, refers to his decision not to "re-up," using the Army term for re-enlistment, rather than "ship over," as it's referred to in the Navy and Marines.
Factual error: When the stolen freight train is braking, the air pipe becomes disconnected. This should trigger the brakes on the train, but the train keeps going with no brakes. When the train is being slowed with no brakes working, why are there sparks coming from all wheels on the train? (00:32:00 - 00:38:00)
