If you go into a cafe in Israel, it’s not quite like trying to board a plane but it’s not just a walk in and sit down experience either. This is, so far, a one-off. And while the man at the centre may be a nutter in some sense, he is not off the planet, but a rational actor fully responsible for what he did and fully aware that the rest of us would judge him very badly for what he has done. Criminally insane he was not. How many more like him there are only the future can tell.
