Corrected entry: When Riggs confronts the South Africans in the Embassy, he beats up two of them before aiming his gun at Arjen, Vorstedt, and the two other remaining South Africans. However, after he shoots the fish tank, there are three South Africans scrambling to pick up the fish as Arjen directs them, and Vorstedt was not one of them (he remained standing ahead of the tank). No-one else could have entered the room, and it isn't plausible that either of the two that Riggs viciously beat would've recovered so quickly.
Corrected entry: Right before a chase ensues near the stilt house, at the point where the hotel waiter hijacks a flatbed truck at gunpoint, notice how its passenger side door has no mirror (all it's got is a metal assembly, no mirror). But moments later when Riggs climbs along the truck and tries to get a better look him, he does so through a passenger side mirror. How did it get there in the midst of a chase?
Corrected entry: The building used for the South African Consulate is actually a bank. When Roger and Leo are thrown out, the glass front doors are marked with winged logos and consulate lettering that is dark in color, but one door has additional white lettering that says "Open to Serve You, Monday - Thursday 9am-4pm, Friday 9am - 6pm"- rather out of character for a consulate.
Corrected entry: When Riggs emerges from the water after he has freed himself from the straightjacket he knocks out the two bad guys using both his arms. This wouldn't have worked as he had to dislocate his shoulder to wiggle himself out of the jacket, and he relocates it only after the fight.
Corrected entry: There's no way Riggs could have got to Rudd's building before Rudd did. Given that Rudd had a head start (after running the red light), Riggs somehow managed to not only beat him, but find a parking spot, steal a sign and be there waiting, while Rudd was doing a straight drive there. There's simply no way.Gavin Jackson
Corrected entry: When Riggs is on the recovery truck, he drops his gun and it lands on the left side of the road, but when Leo picks it up after Roger stops the car, its now on the opposite side of the road.
Corrected entry: When Murtaugh meets up with Riggs before he destroys the stilt house, you hear the tires of both their vehicles screech as they stop, yet they are on a gravel road.
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.
Corrected entry: In the beginning, when Riggs and Murtagh are chasing the BMW the red police beacon can be seen flashing inside the windscreen. When it then cuts to a conversation between Riggs and Murtagh inside the car and you can see the beacon but it's not on. Then it then cuts to the outside of the car and the beacon can be seen flashing once again.
Corrected entry: Murtaugh and Riggs are partners since the first movie, they've been working cases together, drive together, Riggs has extra clothes at Murtaugh's house and yet Riggs had no idea that Murtaugh was having construction done, asking if it was an oxygen tent. Murtaugh is showing Riggs the garage and hobby room as if he'd never discussed it with him before. And it's not as if they just broke ground, the job is halfway complete, with the frame up and all. Obviously the dialogue was done for the viewer, not for the characters.
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: 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.
