The forensic expert who checks the fingerprints on Kathy's belt in the hotel room isn't wearing any protective clothing, even though there is still the danger of being infected, as the virus was released in the ventilation system, and anyone would be still exposed just by breathing the air anywhere inside the hotel. In fact, the other persons in the room (apart from Dessler and Kathy, who have already been exposed) checking for fingerprints are all clearly wearing Hazmat suits.
Chase is leading a strike team to Saunders' location (or so they think). As he and Agent Baker make their way by the cars, the camera clearly passes by a second camera team and crew members hidden inside and outside of a truck just as they turn the corner and take cover behind another car.
When Chase and another CTU agent are running through a car park you can see a blur of what looks like a person in a truck in an otherwise empty lot. If slowed down you can actually see a full crew of 4-5 people as well as a camera.
Throughout season III Jack Bauer keeps saying he believed Saunder died in Kosovo, and often substitutes Kosovo for Bosnia, therefore implying Kosovo is a part of Bosnia. Since Kosovo is not and has never been a part of Bosnia (Montenegro is between them), this is an error. One could also say: "No wonder Saunders didn't really die as Jack believed - there was no chance for him to die in Kosovo, Bosnia, since such place does not exist!"
