Wasn't it the Kurds who announced the capture of Hussein, as well as now (supposedly) Zarqawi?
If Saddam was arrested about 2030 local time and that's 8 hours ahead of us, it would have been 230 Sat afternoon here. If we first heard about it Sunday morning (it was around 6-7 am, right? All I know is I turned on the TV that morning around 9 and it was all over the place), then we had him for about 17 hours before news really snowballed.
So we very rightly could have nabbed him hours ago, last night even, and the news is just starting to come out now. Of course I desperately want this to be true. :)
