Think about all of the trading records lost or destroyed. Can't investigate any of those firms' trading records prior to that terrorist attack. The brick and mortar attack and destruction was a visual nightmare. The human lives lost were the biggest tragedy in the who mess. But the billions/trillions of dollars possibly extorted and scammed from the investment community should be the target of recovery. Some of what is recovered should go to the families of those lost on that day.
Regarding asbestos, tons of it fell on Manhattan that September Morn. Many in the area had no idea what they were breathing. Years from now thousands will likely be suffering from mesothelioma. Again, those responsible, should be held accountable.
