you think that maybe they hadn't already acted and blown up or raided one of the places the man (Z) stays?
believe me when I say he doesn't sleep in the same bed, nor the same city each and every day.
Oh, I believe that he is actively persuing Zarqawi and is itching to either capture him or get a confirmed kill, however, telling the press that we know where he is is pure bluster. If he knew, Zarqawi would be dead or in custody. If the general thought saying that he knew would flush him out, Zarqawi would know it was bluff and wouldn't rise to the bait (he hasn't stayed alive this long by being stupid).
