How Sept. 11 changed American life

In his book Homeland: The War on Terror in American Life, Richard Beck looks at how the Sept. 11 attacks led to the expansion of government surveillance and a sharp increase in hate crimes against Muslim Americans. Beck also argues the War on Terror laid the groundwork for Donald Trump to become president and “impunity culture in American politics.” He spoke with Tonya Mosley. Also, Maureen Corrigan reviews the novel Exit Party, by Emily St. John Mandel.
