I was in New York City on 9/11. Five years ago on this blog, I posted my remembrance of that horrible day. And, as I wrote last year, I also will never forget the days that followed, as desperate family members searched for loved ones and the faces of everyone in that usually vital city reflected shock and fear.

Those who suffered injury or lost loved ones on 9/11 bear the deepest scars from that day. My deepest sympathy goes out to them. Unfortunately, all of us who were alive then to remember the horror bear scars on some level. Let our scars be reminders that violence and aggression should never be perceived as means to an end.
