Professional, The - Resealing Walls
Before Leon axes the air vent, he shoots it up with bullets.
The first camera shot of him shooting it has bullets all around the vent fan.
The second shot of him shooting, the top bullet holes are gone and then he shoots them up again.
The footage sequence must have been switched.
