The cat-and-mouse game does not end there. As detentions at Bagram and traditional renditions have come under increasing legal and political scrutiny, the Bush and Obama administrations have relied more on other tactics. They have secured foreign intelligence services to do all the work -- capture, incarceration and interrogation -- for all but the highest-level detainees. And they have increasingly employed targeted killings, a tactic that eliminates the need to interrogate or incarcerate terrorists but at the cost of killing or maiming suspected terrorists and innocent civilians alike without notice or due process.
The government, however, sees the terrorist threat every day
When one of its approaches to terrorist incapacitation becomes too costly legally or politically, it shifts to others that raise fewer legal and political problems. This doesn't increase our safety or help the terrorists. But it does make us feel better about ourselves.
