When the camera shows a POV shot of the beggar on the roof try to hit Charlie with a large stone block, Charlie is seen drawing out his pistol. In the next sidewalk shot of Charlie, he has not yet put his hand into his pocket.
As Charlie is about to enter the Lamartine bank, leaving his son outside to keep watch, a man in the back-projected scene behind the door is about to leave the bank. A quick edit, and the man disappears before Charlie enters and the camera follows him in.
