When is a law not a law?

The answer, as described by Attorney General Eric Holder in this The Hill article is whenever he or the President wants. 
According to the Attorney General, ""There is a vast amount of discretion that a president has — and more specifically that an attorney general has,” Holder responded. “But that discretion has to be used in an appropriate way so that your acting consistent with the aims of the statute but at the same time making sure that you are acting in a way that is consistent with our values, consistent with the Constitution and protecting the American people.""
Good thing that we have the Attorney General to personally make a decision using his "vast discretion" that the entire legislative body in Congress and the checks and balances afforded through the Supreme Court cannot rightly determine that a law is consistent with our values, the Constitution and protecting the American people.  Whatever would we do without his benevolent guidance is beyond me.  Thank goodness he is on the job, maybe we can just save some money by getting rid of that whole legislative and judicial branch of the government.
