What I'm disputing is the connection between these two things. Hillsborough was not a consequence of overcrowding. The Leppings Lane end as a whole was not overcrowded - the number of people in the stand at 3pm did not exceed the number of tickets sold. The problem was that because of the failure of the police to manage the crowd properly on the day, fans were directed overwhelmingly into the two central pens while the side pens were significantly under capacity.
I'd also add that UEFA and the French government have changed their story so many times already; I don't know why you'd trust them. First there was '30,000-40,000 fake tickets.' Now it's about 2,000. You really think that 2,000 fake tickets caused those scenes?
