On the Hand : After the shot.

No, but it might affect subsequent shots (more of a psychic thing than a physics thing), so the defense gains an advantage if the foul isn't called.

bob,
That's certainly correct.
That's also why it's important for the summer blacktop time to include playing some "Pro-ball" which includes pullin', pushin', jabbin' and stabbin'.
Then, when a player does get an unadulterated shot it's like a gift.
