When Buster is chased off the trash can by the cop, his clothes are dirty and covered with pale dust. As he walks away from the cop, his clothes are clean.
Buster cuts the rope men are using to lift a safe, but after the safe falls, the rope attached to the safe is too short to have reached the men who were pulling on it.
Buster's attempt to hang himself fails because the rope isn't tied to the tree limb at all, and he falls flat on the ground. But when the cops come running over, the rope is tied tightly to the tree limb with just enough slack for Buster to stand upright.
Buster steps off a curb by a narrow street with no streetcar tracks, into a wide street with an approaching streetcar.
