This is a prime example of irresponsible behavior that gives all hunters a bad name. Good shot placement is certainly VERY important and a properly-placed shot will anchor any game.
But, you can just not guarantee a properly-placed shot under all circumstances. Even a well aimed shot can strike bone or thick grissel that will prevent proper expansion and deep penetration.
Even a properly placed 30-06 (180+ grain bullet) may strike bone and not penetrate deeply - the game is left to a painful death, unless good tracking is successful.
I just can not say enough about the irresponsible behavior exhibited here, at least on the part of the adult responsible for her.
