Since the 9/11 terrorist attacks, the Bush administration has repeatedly demonstrated that it does not feel bound by the law or the Constitution. It cannot even be trusted to properly use the enhanced powers it was legally granted after the attacks. Yet, once again, President Bush has been trying to stampede Congress into a completely unnecessary expansion of his power to spy on Americans. The fight is over the 1978 Foreign Intelligence Surveillance Act, which requires the government to obtain a warrant before eavesdropping on electronic communications that involve someone in the United States. Mr. Bush decided after 9/11 that he was no longer going to obey that law. He authorized the National Security Agency to intercept international telephone calls and e-mail messages of Americans and other residents of this country without a court order. He told the public nothing and Congress next to nothing about what he was doing, until The Times disclosed the spying in December 2005. Ever since, the White House has tried to pressure Congress into legalizing Mr. Bush's rogue operation. The administration and its ... supporters in Congress argue that American intelligence is blinded by FISA and have seized on neatly timed warnings of heightened terrorist activity to scare everyone. It is vital for Americans, especially lawmakers, to resist that argument. It is pure propaganda. [The question at issue is] whether we are a nation ruled by law, or the whims of men in power.
