Of Green Screens and Middle Schools

Aside from the fact that putting McCain in front of a massive, unidentified lawn brought the Green Screen speech to mind, the question arises: What is that picture? Why is it there?

Talking Points Memo, with help from readers, found that it is a picture of Walter Reed Middle School, North Hollywood.

In a speech that was not focused on education, in a week where the coastal "elite" has been demonized repeatedly, why a Southern California school? Especially on with the word "Hollywood" right there in its address?

I'm surprised this hadn't occurred to me. But several readers have suggested that perhaps one of the tech geeks charged with setting up the audio/visual bells and whistles for the evening was tasked with getting pictures of Walter Reed Army Medical Center but goofed and got this instead. At first I thought, No, that's ridiculous.

Maybe ridiculous, but what possible context could this picture provide?
