Dragging Me Under Water

The Guardian today quotes a shark attack victim as saying “he was dragging me under water.”  This a good example of prolixity.  Where else could the shark drag him?  Underground?  Under his spell.  Financially down?  No – everybody understands sharks live and hunt in water.  Another example of redundant speech is the question (very American in usage) “Where are you at?” because where are and where you’re at are the same thing.  Cops often ask each other “twenty?” from the ten code 10-20 for location.  I like that.  Brief and to the point.  Although once I heard a silly state trooper say “twenty at?”
