"O’Keefe is an inherently unreliable source with a long history of deception. In 2009, he released videos that claimed to show employees of ACORN — a community social-services agency — offering advice on how to set up a brothel; it later came out that O’Keefe had edited the video to make this seem like it was happening, leaving out the part where ACORN called the police. In 2011, he committed a similar ethical breach in trying to depict then-NPR executive Ron Schiller as saying that Tea Party activists are “seriously racist people,” leaving out the context in which it turned out Schiller was actually quoting two Republicans rather than offering his own views. As recently as last year, O’Keefe was caught editing a video to make it wrongly seem like a Planned Parenthood employee was discussing harvesting and selling aborted fetus organs on the black market."
