From that conference It was used at a time to where they were aggressive toward the officers , and when that was no longer occurring , the water wasn ' t used anymore . And it was sprayed more as a mist . Here is a video of water being used against people who were not aggressive , directly contradicting Kirchmeier byleonardodicapriohlen .

Based off a quick google image search for concussion grenade wounds not an ideal method , I know , no they don ' t cause burns entirely plausible her wounds were caused by one . Also , do you have any evidence for your claimssuch as the IED oneoutside of police officers ' statements which is all your last link was ? Numerous people recorded the events from the other night , and they contradict a lot of what the police are saying . There is at least one instance of police weapons starting a fire among the protestors .
