You give the Justice Dept. a power and they always figure out another way to use it:
When Congress passed the Patriot Act in the aftermath of the 9/11 attacks, law-enforcement agencies hailed it as a powerful tool to help track down the confederates of Osama bin Laden. No one expected it would end up helping to snag the likes of Eliot Spitzer. The odd connection between the antiterror law and Spitzer’s trysts with call girls illustrates how laws enacted for one purpose often end up being used very differently once they’re on the books.

No, not ‘often’ are they used to very different ends. Every time. How many terrorists have been caught at airport searches? Law enforcement is in a constant quest to repeal the constitution. How many millions of americans have had there every communication and transaction spyed upon to catch a guy paying a hooker?
“No one expected it would end up helping to snag the likes of Eliot Spitzer.”
pretty sure top republican operatives expected that very thing.
