I had seen that NYT video and they did a decent job laying out the sequence of events. With all the videos it was difficult to nail down.
I’ve downloaded a good many and had just seen one in regard to Hooter’s Casino and the conclusion an event happened and there were dead bodies inside. In fact, a full video shows people were sleeping wherever they could. The casinos / hotels were all taking in people and locking down the buildings.
At one point there were 17 ambulances in front of Hooters and so people concluded it was happening there. Instead it became a triage area. The ambulances weren’t able to be dispatched to the Mandalay location because of all the gunfire. That’s the reason dead bodies were at that location. It looks like Hooters is about two blocks down the street and provided cover, facing away. Remember also, there were a number of police shepherding the public down the street.
