Possible Motive

Iraqi forces have announced that they'll be establishing a cordon around Bagdhad before conducting security sweeps. Like a lot of folks, my first reaction was to question why would you announce something like that?

Thinking about it, I wouldn't be surprised if they're hoping that the terrorists (screw that misapplied "insurgent" label) make some conspicuous movements in response. Right now, a lot of Iraqi citizens are sick and tired of the bad guys inflicting civilian casualties. There might be some very directed action taking place thanks to tips provided by the locals.
