well if you're talking about it being justified
"On balance, there does not seem to be an objective, factual basis for Lieutenant Pike to have believed that he was trapped or that his officers were prevented from leaving by the seated protesters. Furthermore, there is no objective evidence available to Kroll that depicts any attempt by the protesters to use violence.
Considering all the available evidence—while recognizing that Kroll investigators were not able to interview Lieutenant Pike to learn and report on his state of mind at the moment he used the pepper spray—the deployment of pepper spray does not appear to have been an objectively reasonable use of force. This conclusion is buttressed by the facts that the MK-9 was not an authorized weapon under UCDPD guidelines and that UCDPD officers were not trained in its use."
keep in mind this is the report of the task force assigned to investigate the entire incident that the chancellor spoke of months ago
