Visible crew/equipment: When Reed asks Walters how many kids he has, the moving boom mic casts a shadow on the lockers at the top, left side of the screen. It appears again a few shots later. (00:00:50)
Log 51: A Jumper, Code 2 - S1-E19
Other mistake: Halfway through the show, the officers walk across the street to talk to some young toughs. The school sign painted on the street is spelled "Schol".
Continuity mistake: In the opening scene, an officer is yelling at Reid for trying to give him a dog. There's a gun belt hanging on the locker next to Reid, Malloy comes in and it's still there. Next angle, it's gone.
Answer: This is from Season 1, "The Long Walk." After Malloy and Reed responded to a "211 in progress", the partners later search the area and question a man walking his dogs, and it's this man who tells them the young guy they're looking for drove off in a red convertible, so Reed radios in the added information and clears them. Later, when the partners are driving along, Reed brings up the topic of the criminal's convertible, and while they're discussing it we can see through the squad car's rear window that a red convertible with its black top up changes lanes, and in Malloy's closeup just as they're talking about how the criminal's convertible was likely stolen, we see the red convertible passing Malloy to his left. That's all we see of this red convertible.
