In Dreams Begin Responsibilities - S1-E1
Continuity mistake: She is on an elevator wearing her uniform. The uniform collar does not show her Chief of Police stars on it but when she walks off the elevator down the hall into her office less than 10 seconds later, the stars reappear on her collar.
Other mistake: A police officer is shown at a hostage scene. He has Sergeant stripes on his sleeve, and Captain's bars on his collar. He is one or the other. But not both. (00:11:50)
