What he didn't know (from what I read) is that the fuel in those tanks don't blow easily.
here some more stuff. it might be posted already but I didn’t see it:
Here is the timeline the sheriff’s department released:
10:05 p.m.: First shots fired by the suspect. This was seen on closed-circuit television from the concert venue.
10:12 p.m.: First two officers arrive on the 31st floor and announce the gunfire is coming from directly above them.
10:15 p.m.: The last shots are fired from the suspect per body-worn cameras.
10:17 p.m.: The first two officers arrive on the 32nd floor.
10:18 p.m.: Security officer tells LVMPD officers he was shot and gives exact location of the suspect’s room.
10:26-10:30 p.m.: Eight additional officers arrive on the 32nd floor and begin to move systematically down the hallway, clearing every room and looking for any injured people. They move this way because they no longer hear the gunfire of an active shooter.
10:55 p.m.: Eight officers arrive in the stairwell at the opposite end of the hallway nearest to the suspect’s room.
11:20 p.m.: The first breach is set off and officers enter the room. They observe the suspect down on the ground and also see a second door that could not be accessed from their position.
11:27 p.m.: The second breach is set off, allowing officers to access the second room. Officers quickly realize there is no one else in the rooms and announce over the radio that the suspect is down.
