(Salem, OR)  --  Oregon State Police are rejecting reports that one of its troopers flashed a white supremacist symbol at a Black Lives Matter protest yesterday.  A video posted on social media shows the trooper walk toward a counter-protester while doing the "OK" hand gesture, which the Anti Defamation League says is linked to the white power movement.  The counter-protester then pats the officer on the back while smiling.  OSP says it has reviewed the trooper's body camera footage and has determined the trooper did not engage in racist behavior.  The department says the trooper was using the hand gesture to ask the protester if he was OK following a scuffle with another protester.
