Right before and as Carlson walks into Miles' office while Miles is looking in the air ducts. Miles opens the vent and starts looking with the flashlight, then the view changes and he all of a sudden has a mirror too! Then as Carlson walks in, the vent cover is hanging there, then again a view change with out a pause in dialogue, it shows Miles with the vent cover closed above him. And was that Mile's office? If it was where the hell did he get all those awards, junk, etc........Love the movie, hope the editor never gets another job in Hollywood! Same vent problem when he's in the evidence room and gets the diamond.
