Photographer Focuses on the Story of 9/11

For the past 20 years, photographer Frank Ritter has been documenting the aftermath of the 9/11 terrorist attacks, as well as the rebuilding efforts at the World Trade Center site. His photos capture acts of remembrance, celebrations of heroism, and many other scenes that tell the continuing story of the 9/11 tragedy.

Ritter's photos are now featured in a new book called 9/11 Remembrance. Renewal. Hope. A Twenty Year Journey. He is our guest on this week’s "Cityscape."
