There is a video I cannot stop thinking about. A retired academic, sitting in an ordinary room, in front of an ordinary bookshelf, speaking in the unhurried speech of a man who has spent his life explaining things to 19-year-olds.
He gives his name. He then says words he knows will not only break the law but may also result in his imprisonment.
The words he says are simple enough, but they constitute a terrorist offence: "I oppose genocide, I support Palestine Action."
He is not the only one. According to Defend Our Juries, the organisation coordinating these mass acts of civil disobedience, more than 60 people have now filmed themselves in this way - an escalation from the paper signs of Parliament Square, which carry a sentence of up to six months, into the territory of section 12 of the Terrorism Act 2000, which carries up to 14 years.
Counter-terrorism officers have raided a handful of homes in the Midlands. Devices have been seized and doors broken through during raids. The rest are still waiting.
