Questions.
He took the room that faced that concert.
How was he able to get that many firearms up there without anyone knowing? They have security cams no?
He knew the concert was going to be held then, how long before this event did he rent that room?
Who helped him with the set up?
According to inside sources, the Mandalay has been booked solid for over a month in anticipation of the concert/festival. If so, it was planned for a while.
If the shooter had checked in by Sept 28, then he had plenty of time to “cool off” rather than just “go off”
Premeditated, calculated . . . Plenty of time to change his mind ...withdraw
