This week on Up Close: incarceration. America today stands out as by far the country with the most individuals in jails and prisons.

And then, the imprisoning of certain ethnic groups during World War II is a controversial topic in our history. Contributing Editor for Texas Monthly Jan Jarboe Russell discusses some fascinating parts of that story in "The Train to Crystal City: FDR's Secret Prisoner Exchange Program and America's Only Family Internment Camp During World War II."
