Muslimpress:FBI has arrested a Florida man who they claim is a Jihadist and was plotting to start a bomb attack in the memorial of the 9/11 event. The federal authorities claim that his communications were conversational and his instructions specific. The man who federal authorities allege tried to make it happen -- by offering advice online to someone who was actually an FBI informant -- is now behind bars. Joshua Ryne Goldberg of Orange Park, Florida, has been charged with distribution of information relating to explosive, destructive devices and weapons of mass destruction, U.S. Attorney A. Lee Bentley III of the Middle District of Florida said Thursday in a news release. According to a criminal complaint, authorities tied the 20-year-old Goldberg to the online pseudonym as "Australi Witness" and "AusWitness," a Muslim living in Australia who was promoting jihad around the world. The FBI said it became aware of him through Twitter messages under the Australi Witness handle that encouraged attacks "with your weapons, bombs or knives" on the Muhammad Art Exhibit and Contest in Garland, Texas, before they happened in May. Two men did attack, but didn't get into the building after being shot to death by police.
