(I would have to politely disagree with the "smashing windows is not violence" defence offered by Arthur Baker in his eye-witness account over at Liberal Conspiracy).
Political protest may well be more important in the year ahead. Stuart White led a lot of discussion on this blog about kettling, policing and democracy. It is not good to tonight have the Ten O'Clock News reporting whether the police have "lost their edge" in policing protest. And the media may struggle to work out how not to make violence the threshold of whether and how to cover protests.
So student violence is wrong.
However, some of our leaders may need to be a little nuanced in how they make that argument, a point made by a letter writer, Adam, in tonight's Evening Standard.
If certain Bullingdon Club members had suffered the full force of the law for their student antics, they wouldn't be where they are today.
Let's examine the evidence.
The official line on David Cameron is that he was the one member of the Bullingdon Club who was tucked up in bed with a cup of hot cocoa before any of the traditional smashing up went on - though the Prime Minister in fact managed to run away and escape a night in the cells after being part of a group, one of whom had put a plant pot through a restaurant window.
Boris Johnson is also believed to have been familiar with the sound of broken glass. He appears to have fictionalised his account, by claiming to have been among those who were caught, when in fact he escaped.
Still, he's grown up now. Boris Johnson has now said that he hoped those responsible for violence at the demo yesterday "paid a serious price for their actions".
But fellow Buller members say they were much more responsible than other Oxford dining clubs, because the violence tended to be directed at furniture rather than people.
And then there is the most curious case of Deputy Prime Minister Nick Clegg, who once staked a claim to have out-vandalised the Buller.
Cactusgate. The terrible tale of the student arsonist, who destroyed two greenhouses full of the finest collection of cacti in Germany, and gained a criminal conviction.
Yet it turned out that there seemed to be so much less to it than meets the eye. No charges were pressed, though Clegg says he did some voluntary work.
Cactus specialists in Munich denied any knowledge of the vegetative inflagration. One of Nick Clegg's old teachers revealed that, "There was absolutely no fire at all, it is simply untrue to say otherwise. It was with a cigarette lighter and he held the flame to the plants. He singed four or five, that was all." The Daily Mail went so far as to suggest that the story had been completely invented by Mr Clegg.
If there are one or two students in the bars next week claiming to have been a little bit closer to the Millibank violence than they were, might they be the "heirs to Clegg"?
