William Raspberry: Yet Another "Cry Wolf" Vote

From the Washington Post:

Are they playing with us again? I mean, all that talk about terrorist threats so detailed that the government had to move quickly to raise the alert status to orange and to screw up traffic around the World Bank and the International Monetary Fund.

Is this prudence? Is it a domestic psy-war charade? Or is it an embattled incumbent reminding us that he is a "war president"?
