Two years after the 9/11 attacks, there are still many unaswered questions -- some of them quite simple like: Why did Attorney General John Ashcroft and some Pentagon officials cancel commercial-airline trips before Sept. 11? and Why did the NORAD air defense network fail to intercept the four hijacked jets? and 18 others asked by the Philadelphia Daily News.

It's about time that we hold the Bush Administration accountable for the free ride they've gotten from the tragic events of that day and make them answer some questions. Don't you think?
