San Francisco: Nearly 400 current and former police officers read and contribute to Facebook groups that promote a range of extremist ideologies including Islamophobia and racism, according to a new investigation by non-profit news organisation Reveal. These police officers work in jails and schools and airports, on boats and trains and in patrol cars and many of them also contribute to groups such as “White Lives Matter” and “DEATH TO ISLAM UNDERCOVER”, said Reveal, which is run by the US Center for Investigative Reporting. While some of these groups trade in anti-Semitic and anti-immigrant memes, some are openly Islamophobic, while others are misogynistic or anti-government militia groups. The investigation identified 150 officers involved with violent anti-government groups such as the Oath Keepers and Three Percenters, said the report on Friday. (IANS)
