There was a documentary which will offer some clarification to you which was aired on ITV1 earlier this week and should still be available to view.
Having visited Hillsbrough several times prior to 89' I can totally understand how and why the fans went down the central tunnel that day.
Thing about ALL "documentaries" is that they have an agenda.
They are done solely to put all the blame on one side.
Rarely (if ever) do they say both sides are to blame to varying extents.
The one I saw was as bad as any I'd seen. It could have been done by the Liverpool Supporters Club !
You see these things, you make your own mind up.
Odd how these crushes happened all the time, but never to this level, though.
Odd also that Liverpool blamed everyone but themselves for the Heyshell disgrace too.
The Prime Ministers statement and apology should help people 'make their mind up' on this one
