1. What do they know and when did they know it?
2. What safeguards are in place to prevent the publishing of fraudulent photographs and news stories?
3. Will Israel receive an apology from Reuters?
4. What other photos/stories came from the same source and will they get re-reviewed?
5. After the 911 attacks, Reuters' editors decided to forbid the "terrorist" label on Hezbollah, Al-Qaeda, Hamas, or any other terrorist group because you wanted to be viewed as impartial. Do you believe your reporting in Lebanon is considered impartial to Israelis?
6. Is it time to review the "terrorist" label decision?

Here's a blog post (link from LGF where there's a lot more coverage of this story) by Jeff Harrell about Hajj.
