With that many people there, they know exactly who the people are that did the shooting. I’m sure the silence is just related to the police trying to cleanly tie up loose ends of the case. I remember in that Idaho murder case everyone was on the cops for not having solved it, only to eventually understand that they were just keeping things under wraps in order to have a slam dunk case. When they catch the ones shooting they are going to get the death penalty for sure. Absolute unnecessary nonsense.
