Visible crew/equipment: As the motorbike falls from the highway, just after it explodes there's a very short wide shot of the site with Danny Glover standing by his car and a couple of guys in hard hats standing around (or running for their life). If you look right behind Danny Glover you can see two people, one in a white hat, one in a red, and one of them is holding a camera - they start moving backwards just before the end of the shot. We then see the bike blowing up, then a close up shot of Danny Glover, from the camera we've just seen.
Visible crew/equipment: Right before the truck carrying ammo explodes near the end of the movie, it comes out of the house as Riggs dives for safety. A man can now be seen who should have been visible in the previous shot - looks like he is lighting a fuse and running... and then boom, the explosion goes off.
Visible crew/equipment: Right after Riggs saves Rianne's job, he and Murtaugh are driving in Rigg's vehicle. There is a shot looking through the driver's side window. Pay close attention to the reflection the truck makes in the glass on the buildings, you can see the crew and at least two cameras shooting the shot from a rig.
