Proof that karma does not exist, if one were needed, can be found between seconds 24 and 54 in the above video, as the most egregious of drop-ins is followed by instant wipeout for the victim and some twenty seconds of glorious if ultimately unsuccessful tube time for the perpetrator.

Unless victim had in fact been shagging perpetrator's wife, or had committed some other heinous crime against him. Or perpetrator was subsequently emasculated by the reef, and lay perishing in the shallows, blood dribbling out of his stump of a penis and into the Tasman Sea, as victim sped past on the wave of the day. Then I suppose we could say justice was done.

Let us hear what drone pilot Stu Gibson has to say on the matter:

"One of my first solid clips when i started shooting aerials, a seriously long wave of some mates playing around, usually about 1 set and hour in the freezing so they like to share the waves."
