In the U.S. there are over 500 sanctuary cities—municipalities that limit their cooperation with the federal government’s immigration law enforcement. Although opponents portray sanctuary cities as besieged by crime, empirical data does not bear out such claims. But what actually justifies sanctuary policies in the first place? Do appeals to public health or safety warrant these measures? Or should lack of cooperation be seen as an act of resistance against unjust federal policies? And how should local municipalities respond to claims that they lack the authority to impede federal immigration enforcement? Josh and Ken find sanctuary with Shelley Wilcox from SF State University, author of “How Can Sanctuary Policies be Justified?”
