During a raid, FBI agents are seen wearing SWAT vests, indicating they are SWAT agents. They breach the door, then the show's field agents enter first. In reality, dynamic entries are made by SWAT agents, and the field agents follow later after the rooms are cleared. This is a common TV cop show error, as often detectives are shown doing the same thing.

The FBI supervisor says to enter the rental car into LoJack. The LoJack service is a private company that sells tracking devices that can be activated remotely and then traced with special receivers.
The first factual mistake was the analyst's concern that they could not enter the vehicle without a warrant was incorrect, as any vehicle involved in a felony entered by a law enforcement agency into the National Crime Information Center (NCIC, which is operated by the FBI) automatically triggers a LoJack check. If the vehicle had a tracker, this entry would activate the tracker.
Additional factual mistakes include: 2) Not every rental car has such a tracker (they are several hundred dollars and usually only found on high-end cars or commercial equipment), 3) If it did have a tracker, locating It would not be instantaneous as was shown, and 4) The system would not return such an exact location. The system works by triangulating signals much like a cell phone tracker. It would return an approximate location and the vehicle would need to be sight-verified by someone on the ground.

The FBI agent near the end says she will be submitting the notes to the DA (district attorney) as part of her investigation. The FBI does not work with district attorneys (state or local), they work with US (federal) attorneys.
