An impact evaluation found that the intervention did not improve citizen trust and cooperation with the police, nor did it reduce crime in any of the six countries that received the treatment. Despite the strong commitment of leaders in each context where it was applied, the police implemented the interventions unevenly and incompletely. In addition, the evidence is limited regarding police action in response to citizen complaints about crime in the treatment area [1].
The study concluded that community policing does not, at least immediately and by itself, lead to better police-community relations, nor does it reduce crime.
The study had a coordinated trial design in Brazil, Colombia, Liberia, Pakistan, the Philippines, and Uganda. The interventions reached some 9 million people in 516 treated areas. In the end, 18,382 citizens and 874 police officers were interviewed.
