Shouldn't all criminals be forewarned?

Now doesn't it just make absolute, positive, logical sense to announce ahead of time that you're going to arrest someone? Maybe it's so that Chalabi will be a stand-up guy and make things easy on them by standing still and waiting for the police to show up and arrest him. I mean, that's what he's done every other time, right? Like when he was charged with (and convicted of) fraud in Jordan. Oh wait, he fled the country and has spent the last 13 years dodging the law on that. Okay, like when he was charged with counterfitting and passing highly classified US secrets to Iran. Oh wait, he fled the country on that one, too. I'm actually rather curious why it is we (the US) have not arrested him at this point, since he's back in Iraq, on the governing council, running for President in the Jan 30 elections and generally being publicly available. I mean, as far as I know, the espionage charges (leaking secrets to Iran, providing outright lies to US intelligence leading up to the invasion) and embezzlement (of millions of US taxpayer dollars) were never resolved. But regardless, now that Iraq's defense minister has done the public the courtesy of announcing ahead of time that Chalabi is going to be arrested, who's going to be surprised when Chalabi flees Iraq? Not me. Will be rather interesting to see where he flees to, though.
