Remember those ACORN tapes that were being hailed on this forum as examples of true and proper journalism? Well, turns out they were heavily-edited bullshit, and the way they were portrayed in the media was the result of a failure of journalism. For example, one of the ACORN employees that was shown apparently helping a couple smuggle child prostitutes into the country, actually called the cops on them, yet that little detail went unreported. Due to the tapes, he lost his job and had his reputation smeared. Why? Nobody bothered investigating the claims made by the people who made the tapes, until criminal charges were brought against the ACORN employees in the tapes. After the investigation, the were cleared of all charges, and the original tapes have apparently now been released. Source.
