Just before Paula Jellison runs out of Charlie's hotel room she grabs her jacket and puts it on. She does not have her her purse as she leaves the room. When appears at the entrance to the hotel on the street she is carrying her purse.
The police go to the laundromat to apprehend Kimble. As the police officer starts to go up the steps to Kimble's apartment, Kimble opens his door and looks down the steps. As he does so, he cast his shadow on the wall at the foot of the steps. BUT when Kimble looks down the steps, the light in his room is behind him and could only cast a shadow against the wall at the top of the steps. In order for Kimble's shadow to be cast DOWN and against the wall at the foot of the steps the light would have to be ABOVE and behind him, NOT just directly behind him.
