A NASCAR driver tweeted this morning that the worst possible thing is for an athlete/entertainer’s fans hurt at one of their events.
That said, in a case like this, her best action would be to issue this statement followed immediately by “this is not about me. My opinion and feelings are meaningless. All attention should be toward mourning the dead, comforting the injured, respecting their privacy and obliterating the animals who perpetrated this, up the line to their commanders. There will be no further comments from me”
I have no doubt that this event will not change her in any positive way, rather it will feed into her narcissism and simply giver her a chance to make it about her.
