Given the number of 'Lone wolf with mental issues' attacks that have been carried out over the past few years I'd suggest that sectioning the lone wolves mayn't be a bad idea.Not the same thing at all. World of difference between verifiable mental illness and political views someone doesn’t like. I don’t like it any more than you, but it’s an unfortunate consequence in living somewhere that doesn’t resemble the former E Germany.
If you have evidence you can convict, if you don’t you can’t. Deriding ‘innocent until proven guilty’ with memes like ‘bureaucratic luvvie’ and ‘innit?’ is just playing to the crowd.
