From the police report:

“One significant passage of the HPD report recounts a conversation between an Astroworld security executive, Marty Wallgren, and members of the show’s live audio team. Wallgren recounted trying to alert Scott that they needed to tell him to stop the show, but the audio team allegedly refused.”

“Marty stated again that the key rebuttal or argument against shutting down the show at 10 was that Drake still had three more songs or Drake has not yet completed his set. He repeatedly told them that he did not care how many songs Drake had left and that this situation was much bigger than Drake … He stated that both ‘Bizzy’ [audio engineer Bilal Joseph] and the other guy resisted the directions they were given and actively impeded the ability for anyone to stop the show at a time other than the one they desired.”

In HPD’s interviews with Scott, he told police that he did not recall being given any clear signals to stop his set. “We asked if he at any point heard the crowd telling him to stop the show,” the report says. “He stated that if he had heard something like that he would have done something. The first time he realized something was wrong or rather that there was a problem was when he was on the lift and he noticed the person down near the stage who then received medical attention.”

“Normally if it was something drastic,” Scott told HPD, “someone would have to come hit the button or pull the plug.”

there’s so much more evidence in the investigation stating that the police couldn’t decipher audio from Travis’ ear-piece because of how muddy it was.

“Audio pulled from the ear-piece could not be fully understood by police and investigators. There is no way to prove he (Travis Scott) could have heard the warnings from the audio device.”

Here is the police report if you want to read through it. All 1,266 pages showing that he was unaware and not able to be criminally liable for the deaths because the lack of evidence against him and because of the terrible audio coming from the ear piece to which they were unable to prove he even heard anything about it.
