From the video it does not look like the officer had a helmet for whatever reason. Different group of officers with different equipment issued? Came off during a scuffle with mob? Not secured?Not excusing throwing a fire extinguisher at the officers, but with the helmets they were wearing does it stand to reason that is what caused his death? Don't know much about the equipment.
A helmet is not a preventative for all blunt force drama, it depends on what purpose was designed for.
