In a reanalysis of the Milwaukee Domestic Violence Experiment, we exam
ine whether the use of fair procedures on the part of police officers
called to the scene of a domestic assault inhibits subsequent assault.
Consistent with expectations, we found that procedural justice did su
ppress subsequent violence, even in the face of adverse outcomes. When
police acted in a procedurally fair manner when arresting assault sus
pects, the rate of subsequent domestic violence was significantly lowe
r than when they did not. Moreover, suspects who were arrested and per
ceived that they were treated in a procedurally fair manner had subseq
uent assault rates that were as low as those suspects given a more fav
orable outcome (warned and then released without arrest). The suppress
ion effect of procedural justice did not depend on the personal charac
teristics of suspects.
