People now forget what happened at the time was normal. So 40 years, 30 years later, people can't say that wasn't normal. (unfortunately) It was how it was at the time. Not only at football matches, but across society in general
And let's be honest, Thatcher, the establishment, and (racist) Police were worse than the fans.
It was a free for all on Saturday afternoons, just as much for the Police as it was for the fans.
I witness loads of police charges, including horse charges, down Claremont Road after the matches. Police brutality, unwarranted arrests, etc.
Football fans in general were treated like shi* by the Police no matter where they went. Not only did you have to dodge and fight opposing fans, they had to do the same with the Police.
Thatcher was Prime Minister from 1979 to 1980. She facilitated and oversaw mass (youth) unemployment, deprivation, poverty, etc, which eventually culminating in the national riots, and national civil disobedience.
Crazy times!
