Jeff Sessions claims that sanctuary cities have more crime. He’s wrong

[He announced, “According to a recent study from the University of California, Riverside, cities with these policies have more violent crime on average than those that don’t.”]

...

[In fact, our study suggests a different conclusion: Municipalities that chose to designate themselves as sanctuary cities for undocumented immigrants experience crime rates no higher than THEY (that sampled subset of sanctuary cities) otherwise would.]

Fake news. That's not a "different" conclusion; that's a conclusion about completely different criteria. For him to be "wrong", they'd have to show that the violent crime rate for sanctuary cities overall is not greater than that of all other cities overall.

They only included a few cities in the stated study (they are not listed in its abstract).
