Outside just after the Bank Robbery, when Kiera starts to chase the Liber8 group down the alley, the shotgun that was laid on the trunk of the Grey 4-Door car at the Alley's mouth is missing. Also the drivers window in now rolled down all the way, and the rear driver's side window is rolled half way down. These windows were closed and not broken a few seconds earlier.
Sam Cameron, son of Greg and Kiera Cameron, has brown eyes, but both his parents have blue eyes. Sam's brown eyes are a factual mistake unless Greg is not Sam's biological father. Although a recessive genetic trait, the offspring of blue-eyed parents will have blue eyes.
(at around 35 mins) During the bank robbery, the man with the shotgun fires all his rounds and says he is out of ammo, but there is a full rack of 6 unused shells on the side of the shotgun.
