At what point are video and sound getting out of sync?

At 12:50 the policeman slams shut the door of her car and it is in sync with the audio.

At 25:55 the same door gots slammed, but no sound is to be heard. Maybe because the policeman is carrying the microphone? Is he that far away?

At about 48:00 the door of another car gets slammed. Its clearly on the audio, but about 1 second too early.
