Continuity mistake: Danny and the ESU enter the warehouse basement to find Bobby, and when they start to return fire, the first guy they shoot knocks over the white plastic lawn chair (beside the recliner) as he goes down. Then, in the next shot facing the door, that white lawn chair is upright (not the yellow table chairs), but in the next shot it's lying on the floor again. (00:32:40)
Frank Reagan: And I don't have a Teflon suit. Everything gets to me. Every time one of ours is hurt, or jammed up, or he's in over his head, it gets to me. I just don't show it, 'cause I can't show it, 'cause nobody wants, or needs, a sensitive police commissioner.
Sid Gormley: OK.
Frank Reagan: So screw you!
Sid Gormley: Yes, sir. That an order, too?
Frank Reagan: Yeah, that's an order.
Sid Gormley: Screw me. I'm on it, boss.
Trivia: Although Len Cariou plays Tom Selleck's father, he's only five years older than Selleck.
