Today is the ninth anniversary of the bombing of the Alfred P. Murrah building in Oklahoma City, a despicable act of terrorism that killed 168 people. This is what I wrote about it two years ago. My thoughts and prayers go out to the victims and their survivors. We must never forget them.

UPDATE: April 19 was a busy day in history - the Shot Heard Round The World in 1775 and the beginning of the Warsaw Uprising in 1943 share this day as well.
