A scholarly lecture in Hilo on Sunday August 22 was disrupted by Hawaiian sovereignty activists.  Ironically, the lecture focused on Islamist violence and raised the question whether Hawaiian sovereignty activists might become radicalized in the same way as the Islamists.  The Hawaiian activists didn’t like the topic or the facts being reported.  Sovereignty activists have behaved in similar ways at other public events as documented later; including threats of bodily harm to schoolchildren and to adults at an attempted Statehood Day celebration.  
For more details about what happened at the lecture in Hilo on Sunday, see an article in the libertarian-oriented Hawaii Political Info online newspaper, at
