The 9/11: Reclaiming Ground Zero documentary will restore your faith in democracy.

Developers and officials wanted to rebuild, but New Yorkers had their own ideas. Some wanted the Twin Towers rebuilt exactly as they had been, others thought nothing should be built on the site, and others wanted to see a total transformation of Lower Manhattan.

And eventually, they reached a consensus: the footprints of the Twin Towers should remain untouched. That public response helped force officials to reconsider their original redevelopment plans and chart a new course, leading to the memorial that exists today.

Can democracy actually work when people profoundly disagree—when people are grieving, angry, frightened and convinced they're right? This story shows us that yes, it can.
