The ACORN Scandal: Videos used voiceovers
Looks like the ACORN video was a hatchet job after all:
"The videos that have been released appear to have been edited, in some cases substantially, including the insertion of a substitute voiceover for significant portions of Mr. O'Keefe's and Ms. Giles's comments, which makes it difficult to determine the questions to which ACORN employees are responding. A comparison of the publicly available transcripts to the released videos confirms that large portions of the original video have been omitted from the released versions."
