Journalist Laurie Garrett was there, in the streets with her notepad and her camera just minutes after the World Trade Center came under attack on September 11th, 2001. She’s written a new book -- a ten-year effort -- called I Heard The Siren's Scream. This hour she’ll share with us her recollections of the 911 attack and what it meant for New Yorkers and for all of us...how it still shapes our relationships to each other as Americans.
