Violence as a health issue

I stayed up last night until 2:30am. An acquaintance makes videos about neighbors and (wow! sorry for the digression, but I just looked up to the sky; an awesome full moon is positioned against the still light blue sky) how disturbances affect their lives. He looks at the violence as psychological, emotional, mental and physical health issues instead of law-related. Disturbances include excessive noise such as car stereos, over-populated and/or noisy houses, littering, public urination, vandalism, etc.
The reason I couldn't get to sleep - agitation about something that appears going on in my neighborhood. I've called the authorities, but even while I know they are checking it out and that it takes time, it's unsettling and annoying to see the continued activity. We've had drug houses here in the past (not saying this is a drug house, but I'm realizing over the last years how, when we live with this stuff, how absurd and inane it is that we become desensitized and treat it as an everyday occurence.
For instance: On Saturday I called the police and said I wanted to talk with an officer and be assured that something was being done or I would make a tremendous nuisance of myself with people connected with this activity. I don't want to do that, because what it essentially does, is simply move a 'problem' from one block to another. I don't believe that's an suitable answer.
After seeing a black and white pass my house three times without stopping, and I had not received a call-back, I went outside to pick up litter as I wrote down car makes and license plates. I glanced up the block and saw two or three squads blocking the next intersection. A friend was outside and we chatted, while another three squads blocked the intersection to the south of us, half a block. Later, I thought, all these squads blocking someone and here we are chatting as if it's nothing.
I also realized how hyper-vigilant I've become to sounds of different cars and which ones park where - and do the blink headlight on and then off, wait a few seconds and repeat. I even have photos of what appears to be a drug exchange (taken from my livingroom window). We recognize cars used by several drug dealing scum and know the street names of several. I even know the given names of some and am sorely tempted to greet them with these names (which they don't like).
There is something to changing the frame of how we look at these occurences. Perhaps it offers nothing more than a fresh look. And that's all right. I hope, though, that it changes how we take action against these activities and perhaps WHO takes action. If it's a health issue, wouldn't that superbly broaden the circle of people who could make change and have been effective in other areas?
