"Casualty" includes wounded and "mass shootings" I think are currently defined as 4 or more casualties in one spot, so it qualifies technically. After seeing the crowd breakthrough and surge, it isn't too surprising that there were injuries. Many stage collapses have had a worse toll. Eight deaths and a bunch of heart attacks from crowding is not anything I remember in the past, it is unnatural, and the security man being jabbed and needing Narcan is definitely a hostile plan.
