Actually, the PT boats I can understand. There are a few dweebs that just hate to fly and I have killed as many as 45 of them in an evening. If you attack a PT properly they havent a chance. The rest though, is a dead giveaway. Obviously this individual is ruthless in his desire to see his name in lights and his butt in a 262.
Of course, the indignant majority could always organize a posse to (likewise) remove all evidence of perks.
