In the early 1980s, a couple of researchers wrote an article in The Atlantic that would have far-reaching consequences. The article introduced a new idea about crime and policing. It was called Broken Windows. The idea was simple: A broken window is a sign of a neglected community, and a neglected community is a place where crime can thrive. The researchers said, if police fixed the small problems that created visible signs of disorder, the big ones would disappear. Today, we explore how ideas sometimes get away from those who invented them... and then are taken to places that were never intended.
