I really hate to hear Chief Moose speak. Every time he says "wif" (meaning "with") I cringe. It's enough to make a guy regret his nickname since 3rd grade (moose).
But, you are assuming facts not in evidence by saying he's in charge. He is acting as spokesman, for some reason. He is in front of the cameras. He is delivering messages. But there's no way in heck I believe that a Police Chief has the power to control so many LE assets. IMO, he's part of the team, but someone else is in charge.
As evidence, consider the fact that every affected jurisdiction is holding essentially the same press briefings. That may mean that a single agency (or bureau) is running the show, but from behind the scenes.
I had an english teacher in highschool with the nickname of "moose." He lived up to it as he was also the football coach. He kept a pinch of Skoal in his lip during class, alowed no backtalk of any type, I tried and got physically slammed against the wall (he was good friend of my dad's and knew he could do it). His real name was Milfred, now which is more appropriate for a football coach? Moose? Milfred?
