Plot hole: When Spartan jumps through the window in the excavation scene of the museum, he crashes into a room with bottles of drink on the shelves. Surely this room too would have been filled in and the window smashed during the earthquake, and the museum wouldn't have bothered to excavate it as it can't be seen from above due to the blanked out window. So what is that room doing there? (00:49:20)
Suggested correction: It is not an excavation. It is only made to appear like an excavation for the museum; it is all decor to display the 20th century items like the car.
Plot hole: Even if the 30 bus passengers that were already dead had been burned up in the explosion of the building their bodies would still have been autopsied after the fact, thus proving that Phoenix had killed them beforehand and vindicated Spartan.
Suggested correction: Considering a building fell on the bodies it would be extremely hard to determine the actual cause of death. Phoenix also could have killed them in a way that doesn't easily show in an autopsy, like asphyxiation.
True, but why would they take the word of a known murdering kingpin over a police officer that while may not do things by the book, has always been for the greater good? It just seems way too far fetched.
The lack of soot and other ignition debris in the lungs and tracheas of the dead bodies would have immediately told the pathologists and coroners who examined the bodies that the hostages were dead before the building was destroyed by an explosion supposedly set off by John Spartan. It doesn't matter how badly mangled the bodies were - a tissue sample no bigger than your little finger would have told them everything they needed to know. John Spartan did not commit manslaughter.
