Corrected entry: Mr. Jeremy's assault rifle at the end of the movie has a silencer at the end, but it is just as loud, if not louder, than Riggs's submachine gun.
Corrected entry: On the video,when Riggs does the last target practice, he only shoots 7 shots, but when the target comes up there are two shots for the eyes, one for the nose, and five for the mouth, for a total of eight.
Corrected entry: When Amanda lies on the roof of the car we see the shadows of two people walking by, obviously taking no interest in the rather peculiarly positioned dead woman. Even in an uncompassionate City like L.A. one should expect that passers-by take at least a closer look at an accident scene like this one. (00:04:10)
Corrected entry: After Riggs has beaten Joshua, Murtaugh is holding Riggs after he collapses. Riggs is facing away from the action of Joshua getting cuffed, yet reacts along with Murtaugh to shoot him, then collapses again. And where was Riggs' gun the whole time during the fight? It wasn't in his waistband where he always carried it, and no holster. It just conveniently reappears when needed.
Corrected entry: Murtaugh and Riggs believe Joshua is going to Murtaugh's home to kill his family. So they have two uniform officers in a patrol car out front of the house, seemingly guarding Murtaugh's family. Magically, tho, Murtaugh and Riggs have beat Joshua there, and are hiding nearby while the family has been removed. The uniform cops are apparently never told who is coming, what he's capable of, looks like, or is driving, as they are very accommodating when Joshua arrives, and are quickly executed. Considering the events prior, this situation is ludicrously inept. Murtaugh and Riggs wouldn't just sacrifice two officers like that. (01:37:15)
Corrected entry: In the Christmas tree lot scene, an ambusher appears behind Riggs and shoots at the drug dealer on the left wearing a blue jacket. He only gets shot once, yet as he falls backward there are several bullet holes in his shirt.
Corrected entry: When Riggs and Murtaugh arrive at Dixie's house, the boys playing on the street immediately identify them as police officers. The clothes Riggs and Murtaugh are wearing and the car their driving, give no indication that they are police officers. So how could the boys know this? (01:02:30)
Corrected entry: After having visited Murtaugh's house and family for the first time, Riggs tells him outside a story from Vietnam, how he "shot a man from 1000 yards in the windy weather" and adds: "That's the only thing I ever been good at." Talk about understatement. Of course he's nothing else but martial arts expert, ladykiller, wisecracking innocent people's life saviour and bad boys' biggest nightmare who can make it through almost impossible situations.
Corrected entry: When Riggs runs after Mr. Joshua, who is trying to escape in the stolen car, Murtaugh shouts after him that Mr. Joshua is heading for the freeway. How on earth does he know that, especially since Joshua was going into some odd direction which allowed Riggs to shortcut him on foot and get ahead of him? (01:27:25)
