Kai then started attending a city council meeting, which Mr. Chang serves on, about security for the local Jewish community center. Kai states his objections, talking about using fear to control people, though the council disagrees with him and the motion is passed. Kai is later seen harassing a group of Hispanic men on the streets by filling a condom with his urine and throwing it at the men while yelling racist slurs. The men beat Kai up while an unknown person records it.
