For law enforcement, fear and the politics of fear have entwined to create a radical new paradigm. Even the term "law enforcement" has been rendered quaint by the Bush administration. These days, the term of art is "lawfare" —the confluence of police work and military tactics. With Joint Terrorism Task Forces set up across the country to coordinate the work of federal agencies and local cops, the FBI now devotes nearly two-thirds of its resources —some $4 billion —to waging war on terrorism. The approach today is not the traditional police work of investigating actual crimes but the far more slippery goal of preventing terrorist attacks before they occur.
