As much as I would like to say this is a good movie, there are things that don't add up in this film. Technically it would have needed more than one sniper to cover the premises even when plenty of surveillance cameras are installed to track the movement of these trapped residents. Let say that tower block has only 18 floors, the highly-trained sniper would need to be somewhere higher than the roof of that building to shoot at the fire hose that the guy was holding onto while climbing down the building on the other side. Since there was only one sniper (obviously it is impossible for him to be staring at and shooting at all four facades of the building at the same time and it didn't seem like the sniper had installed cameras all over the building, those residents could have all gotten down to the first or second floor of the tower block through the elevator shaft and broken into the flats that have windows facing the other side and climbed down from there.
