I agree, there should be a command center and all comms should go through a repeater where it is recorded.
Another aspect which bothers me:
The family. Sans a lone picture of the father coming out of a grocery store, it contrasts distinctly with ANY other scenario where a firearm owned by someone else - in this case, a dreaded ‘assault weapon’ - was used in a shooting.
And not just in any shooting, but a nearly successful assassination rivaled only by the JFK plot (thus far, though that jury is still OUT).
Under any other scenario the media would be HOUNDING the family, and the media would be using their talking points about the weapon used.
Crickets.
In addition to the on-scene SAC and/or any other liaison/commander, someone in DC is coordinating damage control on a national level, in conjunction with the narrative ‘lone gunman’, ‘8 shell casings’ and ‘sloped roof Cheatle fall gal’.
Even MTG isn’t asking that question...
