Jerry- the guy was in a 6" DEEP footprint. Tiger Woods couldn't have gotten out of it. His best play was to have declared it unplayable and taking a drop. He probably didn't because of the high probability that the dropped ball would have plugged in the deep, soft sand. Pine needles and footprints are different things- the latter are man-made and change the playing areas; I can remove loose impediments out of a waste area at the risk of incurring a penalty if the ball moves.
Tiger- I am not a rules expert, but I'm fairly sure that there's no penalty for cleaning up the disturbed area after the shot. At most public courses I play and a few privates as well, some golfers don't bother to rake regular bunkers; waste areas are treated literally with beer cans, wrappers, and cart tracks all over the place. As maintenance budgets get tighter, I bet we will see more of these unmaintained areas. I can buy a rake for under $10 at Home Depot, hardly a high cost item.
