Once the security gates had been egregiously breached early in the afternoon on the day of the show, all bets were off as far as the venue being able to maintain a safe environment for the concert to take place IMHO.
This was 7 hours before the worst events unfolded after 9 pm.
If that had happened at the World Series also in Houston, just a few days before this concert, I believe the WS would have immediately been shut down for fans to attend.
At that point at the Astroworld venue, there was no way to insure that attendees had been screened for weapons prior to entering. It was a free-for-all from that moment on…..essentially a recipe for disaster.

EACH of the 8 lives lost that night were precious and valuable. ALL of the injured and otherwise traumatized witnesses to this tragedy will be affected forever by what they saw and experienced. THAT is an unspeakable high price for this calamity. And it could have even been worse if other types of contraband had been a factor in what transpired. This is my opinion.
