Question: In the wake of the bioterror attacks, how come we didn't see the FBI get involved with the investigation and subsequent manhunt? Also, with the bioterrorist finally located, how come the SWAT team wasn't called in to spearhead the takedown? In real life, the FBI's Hostage Rescue Team would most likely be the ones to go in after a terrorist.
