New this month Continuity mistake: When Riggs is hanging from the tree, his hands are tied behind his back. When he falls and lands on his back, his hands are still behind his back. In the next shot of him, his hands are now tied in front of his body, even though he didn't have time to do anything to get his hands there.
Factual error: Riggs and Murtaugh are told that Cooper's self defence argument (that Woodcock's pistol fired the fatal shot as they fought) holds up because Cooper's gun is 9mm, whereas the slug pulled from the body was a .358. There is no such thing as a handgun chambered in .358. The only .358 caliber that exists is .358 Winchester, which is a rifle round.
