Other mistake: When Agent Douglas finds Snyder on the roof about to escape on the helicopter, Snyder climbs in a rope ladder. Then Douglas fires 9 shots at Snyder. It looks like Agent Douglas is shooting a revolver, which holds only 6 rounds even when loaded.
Other mistake: When Snyder's assistant gives the address to his nephew, Hammer, he tells them it's 623 North Pacheco. When the Boys and Emily leave for school the number on the house is shown as 580, and there is no 623 because they live in a cul-de-sac.
