I am surprised none of your correspondents confessed to being arrested and fined as a result of the Khrushchev-Bulganin demonstartion in 1956 (Michaelmas issue, 2013). Scores were, including a schoolboy friend of mine. It marked the beginning of a postwar police crackdown on students who, unlike the Bullingdon Club members, did not pay handsomely for the damage they caused.

A few years later there was a similar crackdown on Bonfire Night revellers. Colleges gated their students, and members of gown who did manage to join town in the traditional assault on the Randolph Hotel, Super Cinema and Taj Mahal Restaurant received swift retribution. They were kettled in Turl Street, whisked down the Crown passage, and charged in a temporary police station at the back of Oxford Town Hall.

Next year November 5th passed peacefully for the first time in living memory.
