From the same article:
“Las Vegas cops didn’t find Stephen Paddock’s room until he’d already ended his mass shooting - even though a security guard was waiting outside injured.
Police are facing difficult questions about why it took at least 25 minutes to locate the killer, and then another 45 minutes before to storm his hotel suite.”
Some of the questions that police should already have answers to but we don’t yet know include:
1) Did Campos — after being shot — immediately call 911? Common sense would suggest that this was not a security issue, even if he were to be joined by an armed security officer. Was he trained to use common sense not ignore — i.e. to call 911 before alerting someone in security.
2) If Campos did not call 911, when did he call/radio MGM security?
3) When did security (Campos or someone else) first call 911 about the 32nd floor shooting?
4) After the police received the call from MGM security, how quickly did they react?
There were opportunities for MGM to mess up, for the police to mess up, and for them both to mess up in response to the Campos shooting.
Paddock did something to the elevators that prevented people from getting to the 32nd floor. Somehow tampering with the elevator -- along with the jamming of the stairwell door on 32 -- were intended to give Paddock more time alone. This would also explain why:
1. Campos took the stairs to check out the door alarm on 32.
2. Police originally went to 31 and took stairs to 32.
3. Police took so long to get to the scene. (They spent time figuring out why they couldn't take the elevator directly to 32.)
