I don't wish to get into the rights or wrongs of the miners' strike. Suffice to say had they not effectively brought down the Conservative government with the 1972 strike, or we as a nation could guarantee supply of a national resource it might never have happened. My understanding of the law is that peaceful picketing was allowed, but Scargill's bully boys went beyond that. https://www.derbytelegraph.co.uk/news/nostalgia/flying-pickets-brought-traffic-chaos-1370589
I agree that Scargill wasn't the right person to lead the strike and he made some terrible mistakes, he should have gone for a vote, he would have won easily. It's History Steve and we should talk about it and i'm proud to talk about, i'm proud to be part of it and and i'm more proud of my Parents and Brothers and friends who sacrificed a whole year of their life without any Pay other than £3.00 a day Picketing Money something that will never be repeated.
Any Picket Line i saw, there wasn't any bother, the difference was, when the Picket lines were being Policed by Local Police, more than likely their own sons or relations were miners, they wouldn't do what Thatcher wanted so the Picket lines were more Humerous than anything, Thatcher brought in the MET Police because she never expected the resilliance of the working class and called the Miners THE ENEMY WITHIN, and had no intention other than to crush the Miners [like you say in revenge] it was planned years in advance, from the use of the police and security services to infiltrate and undermine the miners’ union to the manipulation of the courts and media to discredit and tie the hands of its leaders.
Sadly this is what the General Public saw, they never realised what was truly happening because of the Tory right wing press at the time. A typical piece of reporting you have just put up in a link, there's about 50 miners there being labelled flying Pickets block roads etc, now days a dozen protesters go and sit in the middle of the Road and stop traffic moving for hours, Ambulances, people trying to get on with their life, what do the Police Do, they bring them cups of tea. The Miners wasn't Yobs Steve or Bully Boy's, how can anyone accuse someone of being The Enemy Within when all they are doing is defending their livelihoods and trying to put a roof over their head and feed their wife and Kids.
In the end Scargill was right Steve and they did shut the Coal mines [rightly or wrongly] and they used the Notts Miners with broken Promises and they used the tory right wing Press and the Police service to help achieve this
