Actually in this instance it was not the AP but the White House Website, I have just checked the site again because that was the photo I used as my photo of the day and I was curious why I had not indentified them.
For some reason they did not

Well ... I guess the WH site just didn't know who they were. The caption Deb found was from a Salt Lake City site--they were probably able to talk to the Gold Star moms and properly identify them.
I'm not apologizing to the AP, though ;)
It may have been for privacy reasons. I imagine some/most Gold Star family members do not want to be recognized the world over. Just a thought.
