Sept. 11. It's hard to believe a full year has passed since the world-altering events of Sept. 11, 2001.

None of us are likely to forget waking up a year ago to see the unbelievable scenes of carnage from New York, Washington, D.C., and Pennsylvania. Approximately 3,000 human beings were killed on that day. Almost all of them were civilians, simply doing their daily, peaceful jobs, or going about their standard routines. None of them deserved to be killed.
