Data gathered in the study, however, overwhelmingly contradict the conclusions of the authors.
Violent crime rates are, in fact, drastically higher in sanctuary cities than their non-sanctuary counterparts, as is evidenced by the chart the authors used to delineate their conclusion.
While the three assert that violent crime is only “slightly higher in sanctuary cities than non-sanctuary cities,” the very chart the researchers used to delineate their claim shows something else entirely – consistent, significant and growing crime rate differentials between sanctuary cities and non-sanctuary cities.
