This video has been posted twice before as I recall.....to save everyone the hassle, i'll give the general synapsus:
1. use your thumbs....more and more powerlifting meets won't even allow you to use a thumbless grip.
2. it's not the spotter's fault....even if he had his hands underneath the bar, the sudden downward force from all the weight wouldn't have made a difference.
3. this is why at professional powerlifting meets, they use 2 spotters on the sides with their hands locked following the bar up and down versus just one over top.
4. never-the-less a great video to make someone cry every once and a while.
