10 years ago today, coordinated terrorist attacks on New York City and Washington, D.C. killed nearly 3,000 people. It wasn't the first terrorist attack directed against the U.S., or even on U.S. soil, but it was the deadliest, and came at a time of relative peace. Probably most people reading this remember where and how they heard the news. We've often discussed the consequences of the attack: security cordons, ID checks and metal detectors where none existed before, a reexamination of how U.S. policy affects international perception and attitudes, and the encroachment of surveillance policies and technology, to name a few. Today, we don’t want to inundate you with links to tributes and retrospectives, so we’ll offer the only thing we can: a look back at how the day unfolded here
