Homeland Security sure did a great job on this one - NOT!
Napolitano will need a lot of whitewash to cover up the screw-ups that ended up with 180 dead and wounded while she was out demonizing catholics, heterosexuals and veterans.
You mistakenly assume that she wanted to discover and stop terrorist activities, instead of watch them unfold so they can take advantage of them.
Shredder overload....
