The crush outside was nothing to do with ticketless fans. It was because (a) they weren't funnelled down Leppings Lane, as the operational plan called for, precisely to prevent a crush at the turnstiles and (b) because of delays due to an accident on the motorway, many arrived late and the turnstiles were inadequate for the numbers trying to use them.
I wish people would read the Taylor and HIP reports, where the evidence is covered in forensic detail, instead of lies of the South Yorkshire police and The Sun. Otherwise you just make yourself look fucking stupid.
