| Field Intervention (Public) | Before We are testing two interventions: hotspots policing and the provision of municipal services, or a broken windows treatment, in a 2x2 factorial design. The hotspot policing intervention consists of increasing the dosage of police patrolling time from about 55 minutes per day per hotspot street segment (defined in section [sec:Design-randomization]) to 90, divided in six entries of 15 minutes each. This entry time is not arbitrary and is rather based on previous evidence from Telep et al. (2014), which finds decreasing returns on crime control after 15 minutes of police presence. Moreover, police patrols will be given specific instructions on how to distribute entries during the day. Hotspots located nearby bars and night clubs will have three entries during the day and three during the night. Other hotspots will have five entries during the day and one during the night. For hotspots in the control group, police will not receive any special instructions and will be free to patrol as they see fit. Activities while patrolling are standard, i.e. criminal record checks, door-to-door visits to the community, arrests, drug seizures, etc. Also, when necessary, police patrols will focus on problem-oriented policing strategies with support from different police branches as youth and juvenile, or counter narcotics specialized agents. The intervention began on February 9, 2016 and will continue for four months. The research team did not see any outcome data before this PAP was registered. The broken windows intervention consists of sending a municipal team to selected hotspots to clean up streets in order to promote more informal social control by residents. The municipal team will be charged with repairing street lights, cleaning non-artistic graffiti, and collecting garbage every few weeks. The intervention began on April 6, 2016 (at the halfway mark of the hotspot policing intervention) and will continue until the end of the hotspots policing intervention. | After We are testing two interventions: hotspots policing and the provision of municipal services, or a broken windows treatment, in a 2x2 factorial design.

The intervention will include an evaluation of compliance, which will help decide if we move on to the second batch or intensify the first batch. |
