On 5 November 2021, an apparent crowd crush at the Astroworld music festival in Houston, Texas resulted in ten deaths and untold injuries. While the criminal investigation is in its early stages at the time of this article, the music festival undoubtably represents some failures of safety and security planning and execution. The death count and reported injuries are too high to be the normal cost of holding events. Disturbing videos from the event, in addition to statements from concert goers and first responders, belie assertions that initial observations by subject matter experts are impossible until the completion of the investigation. The events at Astroworld are a reminder of the need to “protect the 3Ps” at concerts and special events, and the fact that these activities must be balanced.
