As the 10-year mark since the attacks of September 11 approaches, the images I saw from my house across the Hudson River still are fresh in my mind. It was a defining moment for our country. The event took friends from us too soon, changed our ideas of safety, changed our understanding of the vulnerabilities in our systems, and had a profound impact on all of us, both as individuals and together as a country. As we approach the 10-year commemorative,we pause to reflect the journey 10 years on.
