Ten years after the collapse of the Twin Towers, the mood in New York is redolent with anger and melancholy.
The melancholy of those who want to look ahead but are forced to remember.
The anger of those, unbowed, who seek justice and truth. An immense “doubt” enshrouds the life of one American in three, say statistics.
Investigate 9/11 is a movement which arose in response to the attacks of 11 September 2001.
Parents of victims have come together with thousands of architects, engineers and demolition experts to ask the American government a series of very specific questions.
More than twenty years on, there are still no answers.
