Obama can start here
This link to the broad swath of information kept by the DHS on U.S. citizens gives a hint of where Obama can start to roll back the Bush excesses. The current administration has disappointed us by not addressing these matters.
The right has lately taken up the issue of the Patriot Act, conveniently forgetting that it was a Bush creation and the lefties in this country were aghast at its creation. It seems the nature of government that it will seldom voluntarily relinquish power. Obama could also assume with a reasonable amount of certainty that any steps he initiated towards restraining the information collection would be painted as leaving us prostrate at the feet of Osama.
It is time to give the right what they want: Let's roll back the Patriot Act and these other insidious collectings of information.
