As Abraham Lincoln stated in his Gettysburg address, that the US government is "[a] government of the people, by the people, for the people". In order for Mr. Lincoln's vision to truly happen, we Americans, need to use the grey matter sitting on the top of our heads. I agree that it's a shame when people who would be expected to use their intellect--such as slashdot readers--are simply echoing conspiracy theories that cannot be categorically proven beyond reasonable doubt. I would say that we the people have a right to question the motivation of the White House in proposing NSTIC; and I would expect it to come from my fellow slashdotters. However, questioning alone doesn't solve the problem; we should also provide solutions. That, I feel, is what makes a healthy debate. Questioning alone makes you sound like a toddler asking "why" questions because they are learning about the world around them.
My challenge to everyone who would question the motivation of all the players for and against the NSTIC is this: formulate specific questions based on the documents available about the proposed "national online security system". If your question is based on what's not in the document then say so. The government is capable of doing really well, and miserably failing, and it's up to us "the people" to keep them accountable for the activity of the government.
