Other mistake: The "first time" the minister gets shot, you hear about seven(?) shots when Kevin kills Rabat. Later, you can only see (and hear) 4 shots. (00:41:25)
Other mistake: Gary Sinise is in the hotel hallway and sees various characters going into different rooms. The camera goes over the top of the wall and we see him from above as he enters a room. The camera continues to track into the room perpendicular to the hallway. Eventually the camera passes over the back wall of Sinise's room and we begin to see these other characters in their rooms. This is impossible, these rooms are not behind his but on either side.
