He was a millionaire, retired and apparently stayed in hotels quite often, and traveled a fair amount (ex., 20 cruises).
The fact that he booked a hotel that overlooked another concert at that location isn't really saying much if he routinely booked hotels in vegas (concerts everywhere, often) or elsewhere.
Now, if there is no record of him staying in a hotel in vegas prior to the "Life is Beatiful" event...then I'd say there's something there!
True, but he didn’t “nut up” and shoot into those venues. If he was simply off the rails, why not shoot before? Was this concert a specific target? If he was simply suicidal and want a grand body count and statement, why not go to Chicago and fire on Lollapalooza which had over 40,000 people in Grant Park and Obama’s daughter was there. Imagine the media coverage if she had been injured or God Forbid, killed. Just seems odd..
