An Impossible Silence - S1-E11
Continuity mistake: When Catherine enters the precinct station, the desk sergeant places a small white file box on the counter. There's nothing else sitting next to this, but when the shot reverses, a tall black police radio with an antenna sticking up has appeared there. (00:16:10)
Visible crew/equipment: In "Don't Pet the Teacher", when Jeffrey Stone talks to Albert the janitor, a boom mic briefly dips into the shot over Jeffrey's head. (00:06:10)
