Re: optics/scope
Some very rare individuals (Annie Oakley?) can shoot that distance without a scope, but there was also quite a breeze blowing, which only the very best can gauge/learn to overcome via test-shots, especially if shooting 'instinctively'.
So I believe the shooter WAS using a well-calibrated-for-that-distance scope, and was trained to check the flag for gusts. Missing like that, is not really missing by much, in terms of a paper target. One would still be on the paper, if you know what I mean.
I am more interested in the communications hub. Who was in charge of integrating all the services that were there? There should have been a message that the snipers, who set up only minutes before, already had a target in their sights. I dunno, the sniper's spotter could have said something at least. The SS and others reacted pretty quickly in the seconds after, however, it's the critical minutes and seconds before the shot that has us asking questions.
This always happens in real Safety meetings. One understands how sharp-shooting works, for example, and a proper check would have suggested stringing that flag somewhere else. But inb4: some say that such a flag is always done at rallies. REALLY??
