I'd be willing to bet that one of the main reasons that the majority of Stadium disasters have been at football ground is because the majority of sports played in stadiums with crowds of a reasonable size are football ones.
I'm no expert but i'm pretty sure that standing/sitting hasn't been one of the primary causes for any of these disasters.
I've not sat in one of these "Safe standing" areas that they have in the Bundesliga, but I was under the impression that it consisted of your standard european cheap seat (ie. bit for arse, nothing for your back) then infront of you there was a barrier - almost exactly the same as an all seated stadium except that during the match you can stand up. lean on the barrier infront of you and shout abuse at Darren Mackie.
I was also under the impression that the findings of the Hillborough report have no legal basis in Scotland.
