I would want that person to have some kind of treatment, or I would want measures of some kind to be taken, but expressing support for something and doing it are two rather different things.
There are very unpleasant parallels in the British colonial past. I sat through the hearings in the High Court when the Mau Mau people were seeking compensation. The way in which they had been treated by the British Army in Kenya in 1955 was disgusting and disgraceful beyond belief. We are now going through a horrible, vile period in Syria. We must understand where we have come from and how we will get through this period without denying our own civil liberties and encouraging more people to join in this whole ghastly process.
