Once in a while, a picture just jumps out and sticks to our minds. We go back to it, again and again.

This picture was taken just after a car bombing in Baghdad, and is all over the internet, along with strong emotional responses among the bloggers.

Another picture, published by Army Times, seems to have been taken just moments before, and is credited to Khalid Mohammed / The Associated Press.

Its caption (and credits) probably apply to the above picture as well:

A young boy seeks shelter behind a soldier with the 82nd Airborne Division on May 28 after gunshots rang out in a busy commercial district in central Baghdad. A few minutes earlier a car bomber had blown himself up, killing at least 21 people and wounding 66, police and hospital officials said.
