Are individuals displaying deviant behaviour going to be publicly identified so they can be watched more closely? Or is it 'one strike and you're out'.
I think this might be a point at which we need to try to blur the public/private distinction. Like, we can imagine how someone's husband or wife or children or parents might try to respond to worrying behaviour (in the best case scenarios - in worst case scenarios they're a big part of the cause). I think that sort of response is often much better than an 'outside' response by law-enforcement or mental health services - especially because outside responses usually only come when something serious goes wrong (e.g. people need to cut themselves in order to get help to stop feeling like cutting themselves).
At the moment, we tend to either have people who don't get any 'private sphere' attention, only interventions by anonymous state functionaries, or we have people being supported by family members/friends, who then, taking all of that burden themselves, get burnt out or fucked up - especially because they don't have access to the kinds of resources, training, knowledge, that they need.
So the ideal solution to my mind would be to try to get the best of both worlds: take the resources and skills of the public sphere and make them universally available, but try to dissolve the distinction between 'society' and 'personal relationships' to some extent. What exactly that looks like or involves, I have no clue. But I think that's a good direction to look in.
