Visible crew/equipment: After Prentiss and Morgan catch Eric and his girlfriend in the park it cuts to Prentiss and the girlfriend in the interrogation room, and as the camera tracks backward from the door's window we can see a nice reflection of the moving camera and also a crew member standing behind Hotchner.
