I don’t have anything from an advocacy group comparable to Vera, but here are a handful of research papers from academic journals. You need to understand that the idea that policing has no effect on crime is a fringe activist view that has been mainstreamed by dimwits copy-pasting on social media.

Aziai, Alberto. 2022. “What happens when the police go on strike? Analysing how a marked reduction in policing impacts upon homicides in Ceará, Brazil.” Global Crime, DOI: 10.1080/17440572.2022.2098121 (The [police] strike led to a statistically significant increase in homicides ranging between 110% and 250%…. Even in a violent context, the perception of a higher risk of apprehension induced by police presence acts as a powerful deterrent against homicides.)

Blesse, Sebastian and André Diegmann. 2022. “The place-based effects of police stations on crime: Evidence from station closures.” Journal of Public Economics. Vol. 207. https://doi.org/10.1016/j.jpubeco.2022.104605 (Many countries consolidate their police forces by closing down local police stations. Police stations represent an important and visible aspect of the organization of police forces. We provide novel evidence on the effect of centralizing police offices through the closure of local police stations on crime outcomes. Combining matching with a difference-in-differences specification, we find an increase in reported car theft and burglary in residential properties. Our results are consistent with a negative shift in perceived detection risks and are driven by heterogeneous station characteristics. We can rule out alternative explanations such as incapacitation, crime displacement, and changes in police employment or strategies at the regional level. We argue that criminals are less deterred due to a lower visibility of the local police.)

(Communities expect the police to control violence. Ineffective strategies will undoubtedly undermine police legitimacy. Effective police crime prevention efforts are characterized by changing the perceptions of potential offenders of apprehension risk and by modifying criminal opportunities (Nagin, Solow, and Lum, 2015). Although arrests are inevitable, police should be oriented toward preventing crimes from happening in the first place.)

Braga A., Kennedy D., Pielh A and Waring E. 2001. “Measuring the Impact of Operation Ceasefire in Reducing Gun Violence: The Boston gun project’s operation ceasefire.” NIJ. (The time series shows a 63-percent reduction in the mean monthly number of youth homicide victims from a pretest mean of 3.5 youth homicides per month to a post test mean of 1.3 youth homicides per month. Analyses suggest that the Ceasefire intervention was associated with statistically significant reductions in all time series., including: A 63-percent decrease in the monthly number of youth homicides in Boston. A 32-percent decrease in the monthly number of citywide shots-fired calls. A 25-percent decrease in the monthly number of citywide all-age gun assault incidents.)

Vol. 31(4): 633-663. (Abstract: Our research suggests that hot spots policing generates small but noteworthy crime reductions, and these crime control benefits diffuse into areas immediately surrounding targeted crime hot spots. Our analyses find that problem-oriented policing interventions generate larger mean effect sizes when compared to interventions that simply increase levels of traditional police actions in crime hot spots. We also find that only a small number of studies examine the impacts of hot spots policing on police-community relations. The extant research on this topic, however, suggests that community members have positive reactions to these focused policing actions.

Vol 31(4): 633-663. (Many researchers believe that crime problems can be reduced more efficiently if officers systematically focus their attention on crime “hot spots.” Previously, the value of focused problem-oriented policing efforts in controlling violence was not known. This randomized controlled experiment […] concluded that the Jersey City Police Department’s pilot problem-oriented policing program was successful at reducing crime and disorder at violent places, with little evidence of displacement.)

Vol 40(4), pp. 1047-1082. https://onlinelibrary.wiley.com/doi/10.1002/pam.22323 (During the last decade, while national homicide rates have remained flat, New York City has experienced a second great crime decline, with gun violence declining by more than 50 percent since 2011. In this paper, we investigate one potential explanation for this dramatic and unexpected improvement in public safety—the New York Police Department’s shift to a more surgical form of “precision policing,” in which law enforcement focuses resources on a small number of individuals who are thought to be the primary drivers of violence. We study New York City’s campaign of “gang takedowns” in which suspected members of criminal gangs were arrested in highly coordinated raids and prosecuted on conspiracy charges. We show that gun violence in and around public housing communities fell by approximately one third in the first year after a gang takedown. Our estimates imply that gang takedowns explain nearly one quarter of the decline in gun violence in New York City’s public housing communities over the last eight years.)

(This study sheds light on the improvement of police services by examining the French Quarter Task Force (FQTF) – an anti-crime program in New Orleans’ French Quarter. First, we provide new evidence that increasing police presence is effective in crime prevention. Our difference-in-differences estimates suggest that the FQTF, which increased police visibility in the French Quarter, reduced robberies, aggravated assaults, and thefts by 37.4%, 16.9%, and 13%, respectively. Second, our findings imply that the proper use of monitoring and incentive strategies has the potential to further improve police services. Exploiting the program’s change in management, we find that providing officers with more monitoring and performance incentives led the FQTF to reduce robberies by 22.12 and aggravated assaults by 5.56 each quarter.)

There is a mountain of additional research. This is not controversial among non-activists.

Take that biased, left-wing, Soros funded BS and shove it. Chicago? Better than NY, but the outskirts and its mayor are rubbish. The Russian paper selling dude with a radio station that tried to get everyone out of Rikers more quickly in the 60's. He died in 1971. The original message is long gone. Chicago beats NYC by having more rats. The human type too.
