I don't know. It sounds a bit ludicrous to me, since the officer would have been close enough to shoot the arms or legs. I guess the police knows what is best.

As Vometia pointed out, officers don't really do that. They are trained to aim for the torso, since it is not easy to hit the head or the extremities of the human body. Of course, unless you damage the right internal organs, people can keep going even after multiple shots to the torso, which is why the officer had to keep firing after the first shot.
One could make the argument that the officer should have used a tazer, but asking him to shoot the arms or legs or attempt close range confrontation with the assailant is simply asking for too much.
