When the interview between Jo Danville & John Curtis ends Curtis points to the camera and says "Could you send me a copy of this so I can watch the look on your face?" The camera is behind Detective Danville & therefore the video would not show her face .
When Danville shoots the suspect with her Glock 19 with the magazine removed, the slide visibly Locks open. This kind of weapon does not do that, unless there is an empty magazine in the magazine well.
