I just had a stray thought about McKay.

If David is the shooter (not a foregone conclusion, but a definitely possibility), how hard do you think McKay is going to take it that she went against her better instincts and waited to involve the police? It occurred to me that she may well think that if she or Robby had called earlier in the day when she first confronted him about the boy, the police would have had more time and might have picked him up before he ever got to PittFest. I can see her beating herself up over this. Or blaming Robby.

Anyway, as I said in the title, it was just a random thought as I was doing the dishes.
