There are many famous ground-breaking trials which can define a culture. The Scopes 'Monkey' trial, the Hauptmann trial, all the way up to the OJ Simpson trial.
Well, I think I've found the one that sums up Great Britain today.
It's the story of a gay man out for a night's socialising in central London, subjected to abuse by drunken teenagers (a nice diverse group) who escalated that to a walloping with a handbag, causing the victim to fight back and hit his female attacker with the same handbag.
This prompted the young male of the group to floor the victim with one punch, allegedly uttering that time-honoured chivalrous admonition, "you can't hit girls"...
Then while the victim lay senseless on the ground, these flowers of delicate femininity laid into him with their stilettos. He died 18 days later.
It really has everything, doesn't it?
