http://www.opinionjournal.com/editorial/feature.html?id=110008794 The British Way They say "reasonable suspicion," we say "probable cause." BY DAVID B. RIVKIN JR. AND LEE A. CASEY Monday, August 14, 2006 12:01 a.m. EDT Britain's successful pre-emption of an Islamicist plot to destroy up to 10 civilian airliners over the Atlantic Ocean proves that surveillance and other forms of information-gathering remain an essential weapon in prosecuting the war on terror. There was never any real doubt of this, of course. Al Qaeda's preferred targets are civilians, and civilians have a right to be protected from such deliberate and calculated attacks. Denying the terrorists funding, striking at their bases and training camps, holding accountable governments that promote terror and harbor terrorists, and building democracy around the world are all necessary measures in winning the war. None of these, however, can substitute for anticipating and thwarting terror operations as the British have done. This requires the development and exploitation of intelligence. Despite this self-evident truth, critics of President Bush and the war on terror have relentlessly opposed virtually every effort to expand and improve the government's ability to gather the type of information needed to detect and prevent terrorist attacks, whether in the form of the Patriot Act's "national security" letters and delayed notification warrants (derisively described by pseudo-civil-libertarians as "sneak and peak" warrants), the NSA's once-secret program to intercept al Qaeda communications into and out of the United States, and the Treasury Department's efforts to monitor financial transactions through the Swift system. These, and similar measures, are among the tools that we will need to finish the job.
