My brother has an article up at Nieman Watchdog entitled How the press can prevent another Iraq. It's nothing more than a reminder of basic journalism: don't believe everything a government official tells you; ask for proof. Use common sense.
It's absolutely amazing that any of this needs to be said to professionals. We knew this kind of stuff when we were high school journalists.
And yet, it does need to be said, because for some reason most reporters these days don't do their jobs.
