I would suggest you go back and read these and other IBD editorials and get caught up:
08/22/03 Atta Boy, Democrats
http://www.investors.com/NewsAndAnalysis/Article/410895/200508120300/Atta-Boy-Democrats.aspx
08/16/05 Committeed Errors
http://www.investors.com/NewsAndAnalysis/Article/410956/200508160300/Committed-Errors.aspx
08/24/05 Enabled Danger
http://www.investors.com/NewsAndAnalysis/Article/411238/200508240300/Enabled-Danger.aspx
02/28/06 Bad Atta-tude
No link available
Then why would the IBD Editorial Staff ask the question, “Did we know about Mohamed Atta?”
