i think the jury had no option but to find the fans blameless,they had to answer the question,do you think the fans were to blame,so they had to answer No because the 96 that died were blameless,there should have been a question do you think that the fans that turned up without tickets contributed to the problems,in which case i think the answer would have been yes
There almost certainly were fans without tickets as there were and still are at every big match and there were almost certainly touts outside selling tickets as there always were.
The issue was the control / policing of those crowds of people outside which was very predictable. You can't blame the fans for the police / ground supervisors or whoever deciding to let those people into the ground with tragic results.
If you were outside a ground with or without a ticket, the match about to start, and a gate was opened by people in a position of responsibility would you have gone in or walked away?
You can't get away from the fact that decision and the subsequent response by the authorities contributed by far the most to the deaths. That would be bad enough if it were just a series of tragic errors of judgement but they then tried to cover it up and were aided and abetted by the press.
