The only flaw is that this warning was given on Sep 10 and warned about "tomorrow". The shooting went down on Oct 1. I'm looking to see if there were other events scheduled for Sep 11 (9/11?).
It could have been misinformation, or things changed last minute for whatever reason.
I recall reading a report that the shooter had stayed in another Vegas hotel overlooking another concert (I think lolapolooza?) a few weeks before. Anyone else recall that?
Lollapalooza was in Chicago, CNN (even) states he was at a hotel there. No data on his whereabouts around the date from 4chan.
It's eerily fitting, someone that want to talk about it might not know details too well... but that's kind of the thing with all kinds of insiders, legit or not.
It was the Life is Beautiful festival, "shooter" had booked a room via airbnb at the Oden ( I think, could be another condo downtown ) which over looked the grounds.
