I’ve read the original 1982 work. The authors of the broken window theory speak of the importance of beat cops’ silencing rowdy teenagers and getting loiterers off the streets. Indeed, they viewed these tasks as more important in police work than solving crime.
Wilson, the one who studied with Banfield, focused heavily on low level blue collar crime. Indeed, he was willing to tolerate a certain level of white collar crime if that’s what it took to keep commerce or a big city operating. Similarly, Banfield felt that a certain amount of corruption was actually efficient and productive, and small time clue collar disruptive behavior was the bigger threat.
