The UC Davis officer who pepper-sprayed the students is John A. Pike III, and his email is japikeiii@ucdavis.edu. (Remember, no threats.)
You can also contact the chancellor of UC Davis at: http://chancellor.ucdavis.edu/contact.php
Lieutenant Pike ought to be terminated and charged with assault. Chancellor Katehi ought to be forced to resign. Just sayin’.
Wow, this video is just crazy.
