Is Piers Corbyn really dangerous?

I thought the police statement — bureaucratic, anonymised, bone-dry – got the tone just right. In confirming the arrest of Piers Corbyn on suspicion of encouragement to commit arson, a spokesman confirmed only that ‘a man in his 70s’ had been arrested in Southwark, south London on Sunday morning.

This, for those who missed it, is understood to relate to Mr Corbyn’s fire-breathing (literally: he took his nylon-clad life in his hands with a stunt involving lighter-fluid) speech to an anti-vax rally in the capital. He told his audience, presumably once he’d had a Murray Mint to get the taste of the lighter fluid out of his mouth, that we needed to ‘get a bit more physical’ with those who support restrictions designed to reduce the number of people dying of Covid. He called on his supporters to ‘hammer to death those scum who have decided to go ahead with introducing new fascism’, adding: 

‘We’ve got to get a list of them … and if your MP is one of them, go to their offices and, well, I would recommend burning them down, OK.
