Instantly reminded me of a certain Senator who once claimed that the elk in the state he represented were "domestic wildlife". And he had the gall to use that term during a federal hearing about wildlife who readily and often cross state lines in their daily lives. Should have seen to look on the faces of the sane people in the room.

It's usually a tactical terminology used by those who really don't have a substantive argument. Sound familiar?

Edit: I meant terminology, not that specific oxymoron but any oxymoron used in an argument, especially one used in a legal case.
