The New York Times Editorial Board:
The administration has now lost all credibility on this issue. Mr. Obama is proving the truism that the executive branch will use any power it is given and very likely abuse it. That is one reason we have long argued that the Patriot Act, enacted in the heat of fear after the Sept. 11, 2001, attacks by members of Congress who mostly had not even read it, was reckless in its assignment of unnecessary and overbroad surveillance powers.
Any new law or executive power should be given the Worst Enemy Test: Would you be comfortable with your Worst Enemy having access to this? If it doesn't pass that test, it needs to be revised until sufficient protections are built into it that you wouldn't have any objection to giving them that power, or it should never be enacted.
