Elvis - the 1989 semi was a replay of the 1988 one, same teams, same ground. But there were no problems at the 1988 semi. However, by the time of the 1989 semi there had been a change in police chief in Yorkshire, and the policing at the game was completely different from a year before.
Joeluke, whilst I agree with you that there appear to be some vindictive people out there I think that the majority of the families of those killed just want to know the truth. Remember that the recent inquery found that 41 of those that died may have been saved if different actions had been taken.
Craft, you're right, the actions of these families are no different from those taken by other bereaved people. Only this morning on BBC news there was a lady who was campaigning for pubs and clubs to not be serving alcohol in glass bottles and/or glasses after 9pm because her husband was stabbed to death by someone in a pub with a broken glass bottle.
