On this week's show, I speak with Colby College anthropology professor Catherine Besteman. She has spent her career studying Somali society, both in Somalia and here in Maine, where many Somalian refugees have begun new lives after escaping civil war at home. Catherine explains the causes of that war and the violence it created, particularly for minority ethnic groups. Her explanation of why Somalis had to flee helps us appreciate that every refugee is dealing with trauma.
