Jo Cox’s murderer wasn’t a threat until he was, and by that time he had assassinated an MP. Before that he was just seen as a harmless person with some fringe political views.
It was the same story with the guy behind the 1999 nail bombings, no danger to anyone until he put bombs in the Admiral Duncan pub (LGBTQ+ community), Brick Lane (South Asian community) and Electric Avenue (Black community).
It keeps happening, and I seriously have to ask if people are more concerned about not being seen threatening the rights of far-right terrorists, while ignoring those of their victims. (I don’t believe that @beschizza is doing this, but I have seen other people do it too many times and it sometimes happens here on the BBS)
