Political Violence in Oregon ?

I found this video over at National Review Online. Watch it and reach your own conclusions. Interesting to see if the "main stream media" will pick it up?

The real issue here is why former Governor Kitzhaber, who is the Democrat candidate to be governor again, would appear at an advertised public event that would prohibit the video taping of the event! What is he hiding or why would he tolerate it. Does he change his message according to his audience.?
