“Are Liberal Police Chiefs Correct That Sanctuary City Jurisdictions Lead To Less Crime?”
No, of course not. They are by and large inept, unqualified appointed political hacks who simply parrot the party line.
That's the way you and I think but libs find a way to express it more conveniently: "If one adds the population of the community that has largely unreported crime to the larger population then sanctuary cities have less crime."
The libs no doubt also have an esoteric equation that shows the sanctuary city posture attracts federal funds and thus provides an overall reduction of the tax obligation of local tax payers
