In the below video that has now 8.5 million views and counting there is a big error yet it's understandable as it fooled me until I looked it up. (what hardcore theorists do lol)

"They had three blond daughters, Emilie (aged 6), Madeline (aged 4) and Samantha (aged 3). Now they have two, Madeline and Samantha. The elder girl shown in the photo with Obama is quite obviously Madeline. The family portrait of all three girls was apparently taken in 2010, when Emilie was about the same age that Madeline is now. Obviously the dress is a hand-me-down.

The claim is based on photo taken at a meeting between President Obama and the Parker family. Two low resolution photos of this meeting were used in the conspiracy theory posts:" source >>http://metabunk.org/threads/1054-Debunked-Emilie-Parker-Still-Alive... click the link and just look at the pictures I didn't want to copy the whole post here but it's pretty conclusive after you look at it for a min.

Things do need to be debunked in this movement when we notice them!
