Related, what if we protected the privacy of everyone by default (which is an absolute joke in bourgeois society at the moment), but reserved technological surveillance as a measure applied to violent offenders? I think it would enable us to be less punitive, rather than being moreso - offenders could be released sooner and with more confidence of collective wellbeing, if they could be “sentenced” to constant surveillance with your Militia or whatever ready to intervene in moments possibly before they even offend (eg., when a situation starts becoming very heated)
Dystopian maybe, but less so than caging and psychologically torturing a human, just less familiar…
Honestly, surveillance is needed until a society built on trust can be developed. Think of China, in 1 or 2 generations they probably can do away with the surveillance infrastructure since they have already developed a society built on trust.
