I thought it would be fun to have a transcript of the scanner traffic...for time keeping questions. I found that NPR had some partial transcripts...I'll post the first one and then the link to the whole thing.
The opening minutes: 10:02 - 10:32 p.m.
10:08: First reports of shots fired at the festival — but it's initially unclear where they're coming from.
"We've got shots fired ... at the Route 91. Sounded like an automatic firearm."
"It's coming from upstairs! From the Mandalay Bay. Upstairs at Mandalay Bay. Halfway up, I see the shots coming from Mandalay Bay — halfway up!"
"We have an active shooter! We have an active shooter inside the fairgrounds!"
10:10: Officers report casualties at the concert.
"Just advising, there are people down on stage left."
"Shots fired from Mandalay Bay. There's many people down stage left."
10:12-15: A team deploys in front of Mandalay Bay, while police still try to determine the source of the gunfire.
"We're in front of Mandalay Bay. We're trying to see where the shots are coming from. If anyone can advise if they're coming from Mandalay."
"It sounds like it's either Mandalay or Luxor. We cannot tell."
"North of Mandalay Bay! It's coming out a window."
"Flashes in the middle of Mandalay Bay on the north side. Kind of on the west tower, but towards the center of the casino, one of the middle floors."
"I'm inside the Mandalay Bay on the 31st floor. I can hear the automatic fire coming from one floor ahead, one floor above us."
10:17-19: The officers remain under fire. Gunfire audible in the background.
"Just be advised it is automatic fire. Fully automatic fire from an elevated position."
"We can't worry about the victims! We have to stop the shooter before we have more victims! Anybody have eyes on 'em to stop the shooter?"
"We have multiple, multiple victims. Shots fired right at the medical tent. We've got one shot in the head."
"Hey officers, please stay calm. Just relax. We're trying to get this set up, OK. Just stay calm."
10:20-25: Conflicting reports on the shooter's activities.
"He's still firing."
"It's been a while since we've heard any shots. Does anybody have eyes on the shooter?"
"Be advised, we are taking fire from a very high floor. We believe it's possibly coming from the Mandalay Bay."
"We're getting from civilians saying there might have been three shooters."
"We've interviewed multiple people leaving the concert venue ... saying that there have been multiple people that are shot or were shooting in the concert venue."
10:25-32: A clearer idea of the shooter's location emerges, and a team gets to the gunman's floor.
"It's Room 135 on the 32nd floor. I need SWAT."
"We have a four-man element at the very end of the hall."
"We have a security officer also shot in the leg on the 32nd floor. He's standing by by the elevator."
"He shot down the hallway and hit a security guard."

Each section has the audio and the partial transcript. I'm not sure if each transcript contains everything that's on the audio, each section is about 30 mins. long.
So for roughly 20 minutes LE had no idea where the shooter was exactly.
The thing is the Mandalay Bay staff knew exactly where the shooter was, from the radio calls from their security and building engineer that were in that hallway. The MB staff knew exactly which room they had a shooter in and had not passed on that information?
I was very critical of the LVMPD response, I thought they had been called earlier, and told the info the MB staff had as to location.
Has anyone seen a reference to when the MB staff called LVMPD? This scanner transcript does not refer to a call from MB staff or any information from them. LVMPD response seems to be entirely based on reports of shots fired at the festival. LE were not even sure where shots were coming from when they responded.
Reading this, it is as if there had been no communication with MB staff.
The smoking gun will be the time the MB staff called LVMPD to report to them they had a shooter. I see no reference to any such call in the transcripts.
I thought you might find this interesting, sounds like someone was doing some diversion work in a big way. The LVMPD likely thought all of Vegas was under attack at the time. Considering all of this, sounds like LVMPD was doing the best they could under the circumstances. Crazy night, with all of this going on no way the shooter didn’t have others helping in some way.
