So anyways...... what I don't understand is why so much of the information from shooting is now be retracted by other information. If the security guard was shot before initial firing began on the concert, why were police not already on the floor before the shooting started? Did the guy just not think to call 911 or have the hotel send in help? In a casino in Vegas, I find it hard to believe a shooting on one of their floors goes silent for X amount of time.
There are some holes in the story and I'm sure there will be more to come of it.
