September 11 pictures -- remembering a dark day

These September 11 pictures, including a somber William Harris holding a sub-machine gun in front of the Baltimore police headquarters, are a stark reminder of how our lives changed that morning in 2001.

We reacted with shock, horror and prayer. One book, about a pet goat, became instantly famous -- President George W. Bush was reading it with some Florida schoolchildren when he heard news of the World Trade Center attack.

But once the planes hit -- in New York, northern Virginia and Pennsylvania -- few people were in the mood for reading -- unless it was the Bible.

I'll have more on September 11 in the morning, as we recap interesting novels and non-fiction books about the day. So come back, but in the meantime, use these pictures from September 11 to remember the day
