Walter Reed, um, Middle School?

I can't help chuckling at a minor bit of low-level incompetence from McCain's speech last night. It's not even his fault, though I'm sure someone on the campaign staff might get an early winter vacation. Apparently, the building projected behind McCain during his speech was not, as he might have wished, Walter Reed Army Medical Center in Washington, but Walter Reed Middle School in—no small irony—North Hollywood, Calif. And now the school has issued a statement (via TPM; emphasis in original):

It has been brought to the school's attention that a picture of the front of our school, Walter Reed Middle School, was used as a backdrop at the Republican National Convention. Permission to use the front of our school for the Republican National Convention was not given by our school nor is the use of our school's picture an endorsement of any political party or view.

(The working hypothesis is that a staffer Googled "Walter Reed" and punted.)
