Perhaps the government should remember one of their most-used quotes when it comes to invasions of privacy. "If you have nothing to hide, you have nothing to fear."
And it is indeed true, onfortunately, that the 'leaker' will be arrested; but the Wikileaks people probably not. Not all of them are citizens of the U.S., and while the U.S. has seen no problem in abducting citizens of other countries to "try" them, these are not Muslim "terrorists", so there will be internation outcry and such. The fact that Wikileaks is in the center of the attention will probably protect them.
In Belgium, children are learnt the following: "If everybody would jump in the Scheldt (a major river), would you jump after them?", if they are doing something stupid "because everybody else does it". Unfortunately, our politicians seem to have forgot this lesson, probably the same moment they forgot that they are "Representatives of the People", not "Representatives of the Money"...
Perhaps we should "invent" (the same way they "invented") a new crime: A crime against our freedoms. As this would be an offence even more serious than "piracy", a even harsher punishment should be applied, in line with the glorious European revolutionary tradition when the citizens saw their rights violated. "The tree of liberty must be refreshed from time to time with the blood of patriots & tyrants."
