The "stock footage" that Hillary Clinton used is owned and obtained by Getty Images, and was taken 8 years ago, when a girl named Casey Knowles, worked as a TV extra.
In an ironic twist, the footage that Hillary Clinton used of the sleeping girls for her "3 AM ad", completely legal for Clinton to do, but the girl is grown up now and will be of voting age in November... and will be voting for Barack Obama.
Stock footage is film or video footage that is not custom shot for use in a specific film or television program. Stock footage is of great use to filmmakers as it is far cheaper than shooting a needed scene.
When the Clinton campaign created the red phone 3 AM ad, (seen here) where it asks "It's 3 a.m. and your children are safe and asleep. But there's a phone in the White House and it's ringing... Who do you want answering the phone?", they used older stock footage, which is perfectly legal to do, but the irony is that the girl is 17 now and will be 18 by the time the Novemeber elections arrive and she is a strong Barack Obama supporter.
The Knowles family of Bonney Lake, Washington, was watching the John Stewart Show when they first saw the ad and Brady Knowles, sister to Casey, thought she recognized the first sleeping child in the ad, so they rewound it, watched it again and sure enough, it was Casey Knowles.
According to Casey, "I've been campaigning for Barack Obama for a few months now. I was actually a precinct captain at the caucuses a few months ago. I attended his rally a few months ago and I'm a very, very avid supporter."
She also states that she would like to get together with Barack Obama and create a counter ad.
The family understands that it is perfectly legal to use stock footage, and they even see the humor in the whole situation, although they say they are slightly annoyed.
Amusing, legal and ironic.
