In the scene where the cop goes to the 8th floor bathroom after the deja-vu, the hole they crawled through is near the floor. They go to the slim wall shot and the light from the hole is above them. Later the cop turns into an agent and he shoots. But he's really shooting at nothing because normally, people crawl down in between walls. And since they were all moving downward before agent shot he really hit nothing. Then somehow, Morpheus jumps from near the ceiling on top of Agent Smith. And Neo shoots at the wall but unless they went to the 9th floor to move down to where the agent was in time, Neo really shot at the 7th floor. This bugs me so much every time I watch it. Pick a floor and stick with it please!!!
