Post Dispatch reporter's new book on Gettysburg goes beyond battlefield

Post-Dispatch's Washington correspondent Chuck Raasch joins "Inside the Post-Dispatch" hostesses Sam Liss and Leah Thorsen to discuss his book being released on October 1st. 'Imperfect Union: A Father's Search for His Son in the Aftermath of the Battle of Gettysburg' tells the story of a New York Times reporter's search for his soldier son while shouldering the responsibility of covering the Civil War, and explores journalism at the time as well as the poor medical care soldiers often received.
