In the second scene when Travolta and Jackson go to get the glowing brief case, subtitled, "The Bonnie Situation" the bullet holes seem to be there before the gun shots.

Just before the gun toting kid comes out of the bathroom you can see one bullet hole on the wall behind each of Jackson's shoulders. After the kid comes out and shoots you can see where one of the charges did not go off to make a hole. A few moments later the hole is where the plaster was.
