No, I just think it's concerning that the organiserers rarely are held responsible. Guess it's easier to punish individuals...
Yes, Maciejuk made a mistake, my post was just speculation about how the situation might have been different. Wouldn't even need to be big metal barriers; I'm sure the simple "poles and rope" solution could help.
That could also help with crowd control those places metal barriers aren't possible.
There's one guy to blame for this incident and one guy only.
