“Despite popular accounts, decades of research actually shows that immigrants – whether legal or illegal – tend to have lower crime rates.
Now, our new research shows that designating a city as a sanctuary has no statistically significant effect on crime.
We examined all the sanctuary cities listed by the National Immigration Law Center (NILC). All sanctuary cities included in the study passed sanctuary laws during or after 2002. We define a sanctuary as a city that expressly forbids city officials or police departments from inquiring about immigration status.”
