We do tend to forget, and we do need to be reminded. We especially need to be reminded that nothing, zero, nadda, zip, of any real consequence has been done to prevent another event to need to be reminded of.
I agree that we do need the reminder as we all have short retention spans, it would seem. I disagree that absolutely nothing has been done to prevent this from happening again. That's not true.
From the demise of the Taliban and new leadership in Afghanistan (that put bin Laden on the run) to many arrests of suspected terrorists in europe and elsewhere to the freezing of terrorist-front bank accounts (containing millions) to strengthing of airline cockpit doors and Homeland Security measures and many behind-the-scenes thwarting of terrorist plans, much has been done in a short time, and then, we rant about civil liberties being abridged!
While I agree that wholesale deportation and/or detention of illegal Arab immigrants should be going on - and isn't - I cannot join you in painting the Bush administration with so broad a brush as you use to claim 'nothing' has been done to prevent another terrorist attack on the U.S.
Terrorism is difficult to stop. Ask Israeli's. While there may not be another 767 used as a missile to kill Americans, there probably will be another attack. It's a huge country with 270 million people and lots of freedom. That sort of complicates things and the Bush team is doing a lot to prevent attacks but they're not God and the FBI, CIA and local police can't know eveything or be everywhere.
The photos are chilling and do serve a grim purpose, though.
