>>Actually, the limited number of entrances (not exits!) already killed. A girl died in the queue to enter a rock concert in Zagreb, IIRC 1981 or thereabouts, because someone thought one entrance would be enough and easier to control. The control was not as much against terrorism, we didn't have that back then, it was about making sure nobody gets in without a ticket. The crowd thought they heard music from inside (probably just testing the sound equipment) and got impatient; those in the front got pushed against the railing and so she died.

>The above reminded me of something that I still remember and think about. When I was a teen-age in Ukraine, my older brother and I would go to almost all home games of our soccer/football team. And every time we would be caught in a huge crowd of men pushing everybody (from all angles) against the closed gates. They just could not get fast enough to their seats. I remember often being suspended in the air by men pushing from all angles and barely able to breath. Many times I thought that I would die. And I wonder how many or any people really got hurt badly in those human stampedes and were never reported in the news. We lived in the society that only good news were reported :)

There were quite a few deaths in one of the love parades not held in Berlin.
Apparantly no one was found to be really responsible, so court "action" - years afterwards - left many frustrated/angry...
