Peace Pipe - S2-E5
Continuity mistake: When Johnny calls in to Rampart, Brackett answers and presses the two buttons to record the conversation, then tells Johnny to standby leaving the two buttons depressed, while the drunk driver is brought in. In the next shot, a closeup of Johnny, Brackett tells 51 to go ahead, and in the following shots Brackett continues to listen to Johnny, but none of the buttons are depressed on the tape machine to record the conversation. Then when Brackett gets off the line, he actually presses the tape machine's off button, as if the buttons had been depressed and the conversation recorded.
