End of game "let them play"

[Adam]

Had a newer guy work with me last weekend, and on the ride hime he mentioned a previous game where his partner called a late foul he disagreed with. He then proceeded to mention his end-of-game-let-them-play theory. Our other partner and I quickly shot that down. My thought, which I've probably plagiarized from here:
If you let a foul go that you've been calling all game, just because you don't want to decide the game as an official, you've decided the game with your inaction.
