The placement of the steri-strips was previously Incorrectly identified as a goof. Carol DID place the strips across the wounds. Two strips form an X across the top wound and three strips are placed across the lower wound, perpendicular to the gash.
When Carol is putting the steri-strips on James's facial cuts she put two on his forehead over his left eye and when the camera angle changes there are suddenly three steri-strips even though there wasn't enough time for her to place it and it didn't show her place it.
When Duncan is running away from the police, the police officer fires 3 shots that all allegedly hit him. These would have been gunshots to the back, however when Carol reaches him to render aid, she has to roll him from his stomach onto his back, and it is clearly visible that there are no bullet wounds on his back.
When Carol is putting the 'chest tube', she cuts the man with a screwdriver, but when she pulls it out there is no blood on it.
As Carol is collecting her coat & scarf, she picks up a pair of sneakers. As she's out the door, the shoes are gone.
When Duncan is running from the cop he is shot in the back yet when he is brought into the ER Carol says GSW to the chest.
