Flowing peacefully in the Spring sunshine on Thursday. 40 years ago yesterday was the anniversary of Martin Luther King's murder. I remember reading with horror of that event and the unrest that followed whilst on an exchange trip in France - near Compiegne -I don't think the Raoul's had a television - all I can remember is the French press coverage of the riots and then returning to their house in a Latin quarter that was soon to have its own erruption. On my return to the UK, I was struck by other - English this time - newspapers which covered the sacking of Enoch Powell for an inflammatory speech where he quoted Virgil seeing the Tiber foaming with much blood. That was 20th April - that must have been a long school Easter holiday! - I don't think you can separate those two events - which is rightly why his speech attracted the condemnation it did.
