Corrected entry: When Danny Glover is thrown out of the South African's office, one of the security people turns his hand as if to lock the door. Yet for the rest of the scene, the door is shown the whole time and there is NO lock on the door. This apparent lock-free policy is keeping a whole heap of protesters outside.
Corrected entry: In the scene with the dive into the hotel pool the hotel balcony is protected by a solid wall. Therefore, only Riggs, who was rolling on the room service trolley, would have had a chance to fly over it, whereas Leo and the attacker should have ran into the wall. (00:27:20)NancyFelix
Corrected entry: When Murtaugh and Leo pull up to is house he tells Leo to stay in the car and don't go anywhere. Leo I think he says he's cold so Murtaugh turns the car on. While Murtaugh is in the house the bad guys jump in the car and the guy in the drivers seat starts the car when it was already running.
Corrected entry: When Riggs is explaining to Murtaugh's wife how he found out his wife was killed, this is not how it happens (in the US). No police department would come upon a wreck and not personally (or have the agency where the officer lives) notify Riggs of his wife's death. The police community is too close. Maybe small town PD's don't but LAPD has directives on how to handle family member deaths for officers. Even if Riggs weren't an officer, no police department or hospital or doctor notifies anyone's immediate family of a serious / tragic death by phone and then asks them to drive to the morgue to "sign the body out" (identify the remains). They would tell them to come to the hospital, or wherever, making sure they have a ride, and then tell them about the death in person.
Corrected entry: During the opening car chase, a car pulls out in front of Riggs and Murtaugh and blocks their path. Just before it pulls out, the headlights on Murtaugh's station wagon flash which is the cue for the other stunt driver to move.
Corrected entry: In the opening scenes, Murtaugh and Riggs are pursuing and keeping up with a far faster BMW 635i in a big heavy Oldsmobile Delta 88 Wagon. Anyone who knows anything about cars knows that there is NO way a Delta 88 wagon could keep up with a BMW 635i in any pursuit.
Corrected entry: The equipment that's supposed to protect Riggs and Murtaugh from the ill effects of the loo bomb is more than insufficient: just a vest, no helmet, no face shield, and nothing for Murtaugh's rather endangered private parts. Furthermore, if the mechanism was triggered by the removal of Murtaugh's weight from the seat there would certainly have been a way to simulate the weight mechanically. (00:54:00)NancyFelix
Corrected entry: In the scene where the toilet blows up, smashes through the window and hits the station wagon, it is clear that the windshield on the car has been broken already and duct taped in place.
Corrected entry: At the docks near the end of the film Riggs shoots a guy multiple times and says names Shapiro, Wyler, Cavanaugh, Rika. When his saying Wyler's name his mouth is closed.
Corrected entry: After he's been thrown into the water, Riggs dislocates his left shoulder, but hits the car with his right shoulder to relocate it. (01:24:45)
Corrected entry: When Riggs is thrown underwater he dislocates his shoulder to free himself, and as he does this he properly just rests his right arm at his side. However, once the jacket thing is off, he spots Rika and frantically swims to her. When he does this he uses both his right and left arm. After dislocating my shoulder three times, I can guarantee you it's nearly impossible to swim like he did with even the lightest degree of a dislocated shoulder. It's not a matter of being able to deal with the pain of moving your arm (which at that moment Riggs probably could've done), but the fact that a dislocated shoulder doesn't allow the arm to flex/move or rotate much farther than from your side. This is also made apparent as a deliberate 'mistake' when he climbs up and kills both men, then reduces (relocates) his shoulder. A dislocated shoulder pretty much limits most movement of said arm.
