Cumulative ATT per 100 officers in the 24 mo after training by adoption time. The cumulative ATT represents the total reduction in each outcome in the months since the onset of training. Early adopters are those officers trained in the first training phase, encompassing the first 17 mo of the rollout. Late adopters were trained in the second phase from months 41 to 63. The study period ends in month 63 for complaints and use of force and month 58 for sustained and settled complaints. Consequently, the cumulative ATT for late adopters extends for a maximum of 23 mo after training for complaints and use of force and 18 mo for sustained and settled complaints.
