I agree. I think it helps them see the people they "serve and protect" as better humans, and themselves as something other than the most righteous thug.
Cop life is so complex that a weekly home economics shift isn't going to repair relationships, normalize psyches or adjust attitudes.
There's a depth of behavioral psychology to this problem that extends well beyond imagining a one-size-fits all therapy plan.
This can't be approached from the perspective of an outsider's view of what plays well to the public concept of what ordinary people imagine about police.
I'm not sure if there even was a time where these things were enough, but right now they certainly don't outweigh the psychological devastation which almost inevitably follows being on duty for a couple of years.
I don't know the reasons but I'm sure there are many, ranging from cultural shifts in society to particular regulations they use to operate.
Still, the fact remains that the job is nowadays really bad. It's hard for people who never experienced it to understand how bad it is. An analogy which often speaks to programmers is: imagine the worst case of big corporation you can, stuffed with dick-head managers, full of pointless activities which obviously contradict each other, and so on. Now imagine every single manager above you can put you in jail for almost anything - but doesn't have to, if they don't feel like it - and that you are one weird rumor away from being fired (or worse). And that's on top of actual job being shitty, tedious, sometimes pointless, always psychically and emotionally draining.
All this is to say that I agree that "one day a week of social positive work" wouldn't help very much.
The bigger problem is to figure out whether the extra expenses are worth it.
Police officers need to have an 'edge' that is missing in normal people. Normalizing their experience with people and re-humanizing them isn't the best idea for their career and longevity in this day and age. Let them burn out in peace or find a way to cope with their distance from people (usually alcohol, seen that a lot).
The effect is the one you noticed in the 70s. From a normal citizen's perspective, the fear factor isn't there. You are generally OK so long as you cooporate, even if you tell the police to fuck off while still doing what they say. Some of this is culture: For instance, someone with a bow and quiver on their back walking through the summer palace that is here in town doesn't get harassed. There are fewer guns on the people.
I'm not sure about your outlook, however. I think they need the humanity to be able to treat people well. After all, normal people are the very people that become cops: That "edge" is a learned thing - just like it is in the military. Minimally, I'd go with a few years of training being mandatory before stepping out and becoming a rookie. Things like conflict resolution, dealing with the mentally ill, and interpersonal relations.
Edit: Oh, and stress. I'd include classes on dealing with stress in the training.
The dysfunctional approach between police and citizens seems to be more manageable and cheaper and makes candidates more numerous. My cynicism is showing though.
Helping folks, getting to know the 'normal' folks. This is when I get to the problem: I don't know what exactly I'd ask them to do, but it would be things like: Free (or very low cost) 2-hour windows of child care on the weekends to give parents a stress break, delivering hot food to elderly folks, helping some folks with lawn care or organize to repair some houses (at little to no cost to the dweller). Actual community improvements.
What is more common is to have well-advertised PR events and regulations that they live in the area. Simply living in the area without being exposed to the positive sides is not enough in my opinion.
