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?"

In our healthcare system, parents normally make medical decisions for their kids because, we think, children are not competent to make such decisions for themselves. Similarly, we permit doctors to violate or defer consent for mentally incompetent adults. But where do we draw the line for what constitutes ‘incompetence’? Should severely depressed patients, for example, have the right to decide for themselves whether or not they want treatment? What makes a patient so incompetent, they should be precluded from making their own decisions? John and Ken consent to talk to Jodi Halpern from the UC Berkeley School of Public Health, author of From Detached Concern to Empathy: Humanizing Medical Practice.

Whether for counterterrorism measures, street level crime, or immigration, racial profiling of minorities occurs frequently. However, racial profiling is illegal under many jurisdictions and many might say ineffective. Is racial profiling ever moral or is it always an unjustified form of racism? Is there any evidence that certain races or ethnic groups have a tendency to behave in particular ways? Or is racial stereotyping a result of deeply-held biases we're not even aware of? John and Ken share their profiles with Linda Alcoff from the City University of New York, author of Visible Identities: Race, Gender, and the Self.
