UC Davis police employed a brand of pepper spray called Defense Technology on peaceful student protesters. The lowest concentration, 0.2 percent, is authorized for tactical deployment. A concentration of 1.3 percent is powerful enough to stop a bear. The type used on the students has a rating of 0.7 percent. The manufacturer recommends the spray be used at a minimum distance of six feet, yet the officers in this case sprayed it on sitting students at near-point blank range.
