Robert Pinsky reads an excerpt from his book-length poem "An Explanation of America." Then, Terri Jentz, referred to in the poem, and the author of "Strange Piece of Paradise: A Return to the American West to Investigate My Attempted Murder - and Solve the Riddle of Myself," talks with Anne Strainchamps. Jentz describes her attack and the man who she believes is her attacker and explains why closure doesn't replace justice.
