The ladder is/was a permanent access ladder to the roof. Are you telling me that no one that was IN that building walked the perimeter?

That’s kinda what I’m thinking too.
I admit that I’m no planner of security for events like these - but i couldn’t help but wonder why the parking lot behind the GRS building was not manned by a couple of LEO’s to shoo people away? To me, it looks like the shooter walked unimpeded right up to the building.
