I kind of feel for the guy for his initial actions – stuck between and rock and a hard place. If he hadn’t opened the gates, folks would have been injured on the outside.
Having said that, after the initial incident the police actions were reprehensible – preventing ambulances onto the pitch, trying to block supporters from leaving the stands, etc. – and if he had anything to do with that then he should certainly be punished.
My own feelings are that the tragedy was a direct result of the decision to use a football ground with a woefully restricted and inadequate entrance, namely the West Stand/Leppings Lane end, and to give that end to arguably the biggest club in England at the time. Why isn’t anyone who made that decision up in court? And why was a football ground with no safety certificate allowed to host any matches, never mind a FA Cup semi-final?
I was 9 at the time, living in Hillsborough, and I still remember people roaming the streets well into the night desperately looking for family and friends that they’d arrived with and subsequently lost.
