I'll own it.
Right now it looks to me to be intentional negligence, with or without knowledge/rumors of the existence of an unstable 20yo shooter. More likely that he's a lone wolf, but not certain given the supposed sighting of him 30 minutes before the attempt.
I just don't see this being attributed to mere gross incompetence given the earlier sightings and a crowd pointing and attempting to wave down LEO as to the presence of a suspicious individual on the roof. With video to back this up. For 2 minutes.
But no matter what it was, I just can't see any reasoning that can explain away the unguarded shooters perch on that rooftop as being an accident. Even the counter-snipers that took him out should have alerted the security team about an unguarded roof. Security 101.
