“She was yelling, ‘Allah is Satan!’ ‘The Koran is evil!’ and ‘You are a bunch of brainwashed murderers!’” Albeshari told KPIX 5 in an interview last week.

Video of the confrontation posted to Facebook shows a park ranger confronting Sadler about her remarks. Sadler is then seen approaching the camera and apparently hits Albeshari with an umbrella and threw her coffee at him.
