The cases cited in the article were of neighbors asking the police to somehow combat the unruly elements in their communities. It seems like you're under the impression that this is a matter of "nervous prejudices" running wild, like some Salem witch trials scenario. But what would you, personally, think would be the best course of action if one of your neighbors (not you yourself) was a drug dealer whose activities were a constant nuisance, if not a threat to your well being? What would have the police do if they had tried every other tactic at their disposal? I don't know if you have children, but if you did - would you just stoically endure, put them in danger, on the basis that a technique which works might one day be abused?

I know it's lame to say "think of the children!", but when you're talking about drug dealers and the kind of trouble they bring I think it's appropriate. In high school I worked with a lot of kids from bad neighborhoods and saw the effects of living in an unstable environment. If something like this helps out kids like them, I'm all for it.

You want to raise the tenor of the neighborhood, broken-windows style? Then use existing laws or HOA rules about trash and noise. Pass new and draconian ones if necessary. Go wild! But the police shouldn't hold people responsible for their neighbors' assumptions about them. We're supposed to be a liberal society, in the classic sense of the word. If you want to treat someone as a drug dealer, catch them dealing drugs.

Which is clearly false.

"Then use existing laws or HOA rules about trash and noise."

How do you make a noise survey without surveilling people. How do you know which house to surveille without listening to the neighbours?

"In the summer of 2006, police were brainstorming ways to rattle a suspected drug dealer. They had exhausted traditional strategies, including undercover operations, and were left empty-handed and frustrated. They decided to park a retired police car in front of the suspect's house."
