Other mistake: In the scene following the robbery, the four young men, led by Tupac Shakur and Omar Epps, run into a brick court, walled on four sides. Shakur states he's going to keep the gun, despite suggestions that they ditch it. He has a revolver stuck in this jeans, by his left hip. When he is challenged about keeping the gun, he pulls another revolver from his pocket, scuffles with one of his friends and shoots him in the chest - all the while the grip of the other identical revolver is in view.
Continuity mistake: In the rooftop scene, when Tupac Shakur's character is dangling off the roof and Omar Epp's character is holding his hand trying to pull him up, Tupac's character loses his grip and falls to his death from the roof. When this happens, look at their hands - suddenly as Tupac's character's hand loses grip from Omar Epp's hand, his hand suddenly changes from dark brown to white. (Both characters are black) You can see a white stuntman who is supposed to be Tupac's character falling down from the roof.
