Is there a legitimate reason why they always set their gun up directly by the open window? (I mean besides needing to point the gun downwards if they're high up.) I always thought it would be superior to shoot from the second /third floor and pull the gun back from the window because then less people are likely to see your barrel and/or muzzle flash. Also, the quality of the sound might change as well (potentially making it harder to place) if it bounces off a few walls as it leaves the room. But I don't know shit about sharpshooting. thoughts?
