True, stop and frisk is just one of many ways broken windows policing can aggressively target the people, when what's actually needed is to target the environment. Policing has a role in cleaning up run down areas, but it's a small one compared to the infrastructure, urban planning, and landscaping improvements needed to reduce crime. Too much/aggressive policing is just another broken window that needs fixing. It signifies that the area is a bad part of town and sets that area apart from the nicer parts of the city.
