"A bipartisan congressional consensus seems to be emerging: First, the Bush administration's eavesdropping program (or something like it) should be continued to try to avert Al Qaeda attacks. Second, such spying should be subjected to oversight by Congress and the courts, regardless of whether President Bush wants it to be.
What kind of oversight? And how should Congress update the Foreign Intelligence Surveillance Act of 1978 to deal with the unprecedented magnitude of the internal security threat posed by jihadists who covet doomsday weapons? If we get the answers wrong, we will end up with weaker defenses against terrorism, insufficient protections against the abuse of civil liberties, or both."
