I was at Sheffield Polytechnic (now Hallam University) doing a Communication Arts degree during the strike, and a team from the Poly were very active in shooting video of the strike and working with the campaign, though I wasn't involved personally. Coming from Rotherham, I was well aware of both sides of the mining industry, and was quite relieved to be partially away from all that by the time I started there.
But much of the Orgreave battle was captured on video by the team, and I remember the ruckus when the 'official' news broadcasts were shown, as they were very selectively edited indeed, removing much of the contentious police behaviour, but leaving in the miner's. Obviously many people at the Poly had by now seen the rushes that had been shot and were in the process of being logged and edited, and the disparity was clear to all. I'm sure this footage was offered to news organisations at the time, but it would be many, many years before any of it was actually broadcast - probably on one of the Channel 4 progs I think.
A mate of mine was actually on Sheffield Parkway stuck in a traffic jam, as this quasi-medieval farce wended its way across all six lanes. He said if you'd had banjo music playing in the background it would have made a great comedy sketch. But two large groups of angry men who hate each other, gathered together in a large field with no restrictions, are always going to have a punch-up, no matter what the moral arguments are.
The whole episode has been one big bad vibe around these parts ever since, and the police were generally mistrusted well before Hillsborough. But both incidents are as much about tribal loyalty, flocking behaviour, hysteria and the inevitable reduced capacity for independent thought as they are about politics, control and worker's disenfranchisement. Remember Ibrox stadium in 1971.
Just don't do large crowds, ever, if you like being safe. They're fundamentally dangerous structures. Though a crowd on a bridge is probably the most dangerous structure. There was a famous incident in Baghdad a few years back, when someone shouted 'b*mb' on the bridge over the Tigris, during a massive religious procession with about a million people actually on the bridge - it was jammed solid.
I saw aerial footage from a US helicopter of a 'crater' appearing around the guy who shouted it, as everyone just ran sideways, and hundreds fell off the edge of the bridge, just like the Penny Falls at a fairground, except these all drowned. They didn't even need to use explosives.
