Sen. Joe Lieberman, an independent from Connecticut, last week wrote a letter to Google Chief Executive Eric Schmidt asking him to "remove content produced by Islamist terrorist organizations from YouTube". Google, in a posting on its public policy blog, said it examined and removed "a number of videos from the site, primarily because they depicted gratuitous violence, advocated violence, or used hate speech." However, Google said some videos by alleged terrorist groups were not removed "because they do not violate our Community Guidelines."
