Visible crew/equipment: Brenda walks into the interrogation room to question Koslov. When we see Brenda on the monitor with her back turned, the outline of her mic transmitter bodypack is visible at her lower back, then as she takes a seat across from Koslov, we see the mic transmitter behind her.

Saving Face - S3-E3
Revealing mistake: After they drop the casket and Provenza says 'guess you can take it with you!', the close up of the dead girl shows her close her mouth.
Continuity mistake: Lieutenant Provenza is showing Brenda the video footage of the (innocent) suspect in a parking lot far from the crime scene at the time of the murder he's accused of. This proves him innocent, but the suspect has been said to be there for 8 minutes, time enough to 'do a needle', but the time stamp on the video says 10:35 pm when the car arrives and 12:35 when the guy gets into it to leave. 2 hours.
