Factual error: Kate is said to have been on the FBI SWAT team since day one, and therefore has never worked a case from behind a desk. However, FBI SWAT teams are composed of regular field agents who respond to tactical scenarios only as needed, and otherwise carry out normal investigative duties. Unless this is the most overworked SWAT team in history, Kate would certainly have handled at least a few cases from a non-tactical perspective.
Factual error: The lightbars seen on the Mexican Federal Police trucks in Juárez are incorrect - they show both red and blue lights to the front, but actual MFP vehicles show only reds to the front. This is very interesting considering every other detail of the MFP vehicles and uniforms is accurate.
