alt Hacker News> Should a person I don't like really have rights, or privacy?
For a society striking a British balance between security and privacy, I'd say it's fair to require people with violent convictions to (a) register public protests they plan to attend and (b) consent to facial-recognition surveillance in public. (One could hash, locally store and potentially hardware enforce the restriction on the device level.)
That doesn't mean I think it's okay for everyone around him to have to give up those rights. And I wouldn't support even that in America unless the individual is on probation.
People need to be allowed to speak in public without having their identities recorded by the police. Also, if you want to follow somebody around who has "violent convictions," you don't have to release them, you can parole them ("released on license" I think I want to say?)
There's a reason you choose to do this during a political protest.
Also, you included a bunch of gambling and tax debts for some reason? Do you think that they are justified because he, and the people who join him, will be publicly avoiding taxes and bookies?
edit: It's also important to note that in the 15th year of future Reform rule, when a "reformed" Tommy Robinson is appointed Home Secretary, he will entirely support drones doing facial recognition during protests. How else are you supposed to catch the anti-Semites?
