That's normal in any large event. People don't understand what is going on or which way they should and shouldn't go. They can also be moved by the tide of people, unable to go any other way, and may be safer where they are. As the article says, police blocked some escape routes. So it goes down to good design, good procedures and matching attendance levels. Something went wrong there.

This is an offensive take on a chaotic stampede where people died. Your linked article even lists the police as trying to stop people from getting out of the way.

>Footage shot as the disaster unfolded showed police officers trying to stop people from fleeing the scene. That could have been because the officers did not immediately realize the extent of the danger, or because they wanted to prevent the stampede from spilling into other areas of the compound.

What it does say is

>Amid the chaos, as medics tried to reach the injured, prominent Israeli rabbis remained onstage, trying to restore calm by reading psalms for the wounded.

your take is wrong and wrongheaded.
