Banning people from bringing in their own drinks is incredibly normal afaik. What no one has mentioned that I’ve seen is: What was the hydration plan of the concert organizers?
Was bringing in empty bottles and filling them inside ok?
How about providing free or inexpensive water once it got past a certain temp?
Misters? Heat relief booths? Onsite medics?
How can we have any clue whether the organizer has any blame if we know nothing about the situation, other than the fact that someone later died?!
Without this info the story is basically pointless - maybe the organizers took heroic steps and a young person got caught up in the excitement with tragic consequences. And maybe the concert provider is a borderline criminal organization who needs to be fined, or shut down, or both. Plus stricter government regulations. But no, we know nothing - thanks Reuters!
