 SPOILER: The FBI was very impressed by the films accuracy in  depicting criminal investigations, serial killers and their victims.  However, they protested against the fact that Clarice discovers  Buffalo Bill on her own, since inexperienced agents are never sent  out alone on dangerous assignments. When Jonathan Demme (qv)  explained to them that he wouldnt change it because it would be the  psychological climax of the movie, they agreed, saying that it would  be the most improbable course of action of all time, never to be  repeated again.
