Chart summary of 1 study examining this question

All answers are assigned by State of K users. The label Mixed means that a study found some evidence to indicate that the answer to the question is "yes" and some evidence to indicate that the answer is "no". This label is often applied when a study uses two or more proxies to study the same phenomenon (i.e. firearm sales figures and self-reported firearm ownership rates as proxies for the prevalence of firearms) and the proxies yield different results when looking for correlations with another phenomenon (i.e. firearm-related deaths). Alternatively, the label may be applied if the phenomenon under study (i.e. whether breast milk improves cognitive function) is true for one group, but not another (i.e. true for girls, but not for boys). The label Insuff. Evidence means that a study found there was insufficient evidence to reach a conclusion regarding the question. The label No Data means that State of K wasn't able to identify the study's response to the question based on the information that was available. This label is often applied when the person creating the list does not have access to the full text and the answer isn't clear from the abstract.

All labels of Literature Reviews and Highly Regarded Source are assigned by State of K. The label Highly Regarded Source, as applied to journals, is a label assigned to the top 20 journals (as measured by the h-index) in various subcategories as classified and reported by Google Scholar. As applied to NGOs, the label is assigned to US NGOs ranked by the TTCSP Global Go To Think Tank Index Reports. The information contained in a source that is labelled "highly regarded" is not necessarily more accurate than information contained in a source without that label.

Increasing Cooperation With the Police Using Body Worn Cameras
"What can change the willingness of people to report crimes? A 6-month study in Denver investigated whether Body Worn Cameras (BWCs) can change crime- reporting behavior, with treatment-officers wearing BWCs patrolling targeted street segments, while control officers patrolled the no-treatment areas without BWCs. Stratified street segments crime densities were used as the units of analysis, in order to measure the effect on the number of emergency calls in target versus control street segments. Repeated measures ANOVAs and subgroup analyses suggest that BWCs lead to greater willingness to report crimes to the police in low crime density level residential street segments, but no discernable differences emerge in hotspot street segments. Variations in reporting are interpreted in terms of accountability, legitimacy, or perceived utility caused by the use of BWCs. Situational characteristics of the street segments explain why low-level street seg- ments are affected by BWCs, while in hotspots no effect was detected"
