OREANDA-NEWS. April 15, 2016.  It was one of the viral images of 2011: a group of college students sitting passively on the ground, and a UC Davis police officer slowly and deliberately spraying their faces with pepper spray, point blank.

The event drew widespread criticism of the school, dragging it into the Occupy Wall Street debate that was making waves around the country.

In the past five years, it appears the University of California at Davis has used a different weapon to cover up that embarrassing incident from search results on Google. Documents obtained by the Sacramento Bee reveal the university paid public relations firms at least \\$175,000 to hide bad publicity on Google when people searched on the university name, and the name of its chancellor, Linda Katehi.
