This report is a response to Vanderbilt University's Latin American Public Opinion Project (LAPOP) critique of our report, "Have US-Funded CARSI Programs Reduced Crime and Violence in Central America?" released in September 2016. That September report was an examination of the only publicly accessible impact assessment of USAID-funded anticrime and community-based violence prevention programs carried out under the umbrella of the US State Department's Central American Regional Security Initiative (CARSI). LAPOP took issue with our illustration of certain methodological flaws in LAPOP's study, as well as with the manner in which we presented our conclusions. LAPOP's criticisms appear to be largely based on misunderstanding and misinterpretation of our arguments and fail to address our main findings. The problems with the LAPOP study that we identified still stand, as does the validity of our conclusion: LAPOP's study cannot support the conclusion that intervention caused the areas subject to treatment in the CARSI programs to improve relative to those areas where no intervention took place.
