Move to a new stadium and all the issues will go away.
Except it won't.
Stadium crowds needs to be managed.
The worst 3 incidents I experienced at sporting events have been.
1) England vs Holland friendly around 1987. Severe crushing and one of my friends who was behind a barrier (which I was in front off) was crying out as he was so scared of being crushed.This was just how stadiums were at that time.
2) Redskins vs Eagles around 2004. Sunday night game and just fighting all around the stadium, no seggration and a really nasty atmosphere. I expect it is the same at all US stadiums, often read about trouble and fans getting killed.
3) Then most surprising. Before the 2016 at Wembley (again, surely that sh*t heap needs to be knocked down and replaced) when there was dangerous crushing probably caused by the escalators to the upper tiers breaking down. Lack of stewards to assist and help, keep everyone calm.
Have only been on the Lepping Lane twice. Once prior to 1989, think it was 1987 against Arsenal and I was in plenty of space under the police box but on TV you could see 99% of the Arsenal fans tightly in the pens and then in 2012 for Wycombe, can't remember any problems that day. However some have said there have been no problems before 1989. Think you have forgotten about Spurs in 1981, Coventry in 1987, Leeds in 1987 and then Liverpool the year before in 1988.
