Before you get too excited about having solved this mystery , officer , I ' ve seen a flash bang take most of a foot off of a suspect . It ' s common knowledge among every LEO here that the officers working that protest are indeed equipped with flash bangs , as all officers in that sort of a situation in the US would be . And , you know as well as I and everyone else here that the vast majority of LEOs have no business being anywhere near a flash bang grenade if they are any innocent people present . You know it , I know it , we all know it . But thank goodness no one at that protest and I mean no one is innocent . We can move along now . <| sep |> here ' s an idea , don ' t put yourself in a situation where you have to 1 v 1 the assassin ?
