Orwellian Speak - "Outrageous/Outlandish Claims"

In recent months I've notice ruling governments the world over lambasting a rash of "outrageous/outlandish" claims against them (for example):

• Downer refuting allegations of DFAT's involvement in the AWB scandal in Iraqi Wheatgate - "Wheat kickback claims outrageous: Downer"
• Rumsfeld's reaction to claims Bush wanted to dump on Al-Jazeera - "We are not going to dignify something so outlandish with a response," a White House official told CNN.

So, is this a new double-speak? It sounds like a denial yet it completely lacks one! So, it's a great way of defusing an issue by appearing to refute the claim yet does nothing of the sort. Anyone can claim something is outrageous or outlandish, but that doesn't mean it's not true. The language we should be looking for is "we completely refute this claim" or "this claim is not true".

So, all Joe Public hears is the "outrageous/outlandish claim" and a few more soundbites thus crushing any chance for the truth to be told.
