especially trained crowd managers, and number one, do a life safety evaluation. so we need to know if the city of houston did a life safety evaluation for that address that would have dealt with festival seating, standing room environments. the victim, the people who died. they're the victims of this disaster. they're the people put into a crowd, into a crowd environment beyond their control. who manages the crowd? not 16-year-old susy, not 18-year-old johnny. the people who organized it. the facility operator, the promoter, the people who approve it. we also need to see the crowd management plan, the emergency plan. and see who was involved in those aspects. that's where you find what went wrong and why it went wrong.
