I know from experience that it is possible that an experienced shooter could hold a rifle steady enough to hit a target 6" in diameter at up to 1000 yards. 100 meters is nothing. When you use a laser sight with a rifle over long ranges (too far to see the dot) you have to use some sort of a magnifing sight to be able to tell where exactly you are aiming. However if the window was closed then the light would have been defracted out of the shooters scopes' sight picture. This would not have allowed them to get the dot to the persons head, since they couldn't see it themselves unless they had a wide-field scope which would let them see the dot even though that was not where they were aiming the gun itself!
