Visible crew/equipment: During Keaton's interrogation at the police station, he's punched in the face. Then it cuts to Keaton being placed in the holding cell, along with the other detainees. As the camera tracks toward McManus, we can see a wired mic clipped directly below Hockney just as he says, "Fenster, will you relax." (00:12:20)
Visible crew/equipment: After Verbal tells Dave Kujan, "Nobody argued with Keaton, they just set their minds to whacking Kobayashi," it then cuts to the office building as Kobayashi and his two bodyguards walk inside. When the camera passes in front of the reflective surface of a pillar, we can see the camera operator, camera on a moving dolly, the dolly tracks, boom pole, and other set equipment in this reflection.

Visible crew/equipment: When Verbal drops the Zippo lighter in the police office, Chazz Palminteri leans down to pick it up. When he leans down out of frame, there are 2 "C-stands" visible in the background. These shiny, adjustable stands are general-purpose utility holders on a movie set, used to position lights and light control material for a setup (i.e. flags, scrims, diffusion, etc).
Visible crew/equipment: When Kobayashi and Edie are meeting, what appears to be a boom mic is visible above Keaton's head when the group is seen through the window.
Answer: You're missing the point: Verbal is making much of the story up. He's changing facts and events to lead Kujan to think Keaton is Sose.
