I am not buying.
How would the city know the names of the people that
stayed behind and the ones who left.
In the WTC a reasonable estimate based on the occupancy of
each client that occupied the offices in the towers could
be made.

You will never convince me that the media did not have
(and have)a clear cut agenda here.
In the end the truth comes out.

From friends, relatives and neighbors, public records and folks unaccounted for. They'll canvass the survivors. Same as any other instance of mass casualties. It'll take some weeks to sort things out.

In the WTC a reasonable estimate based on the occupancy of each client that occupied the offices in the towers could be made.

Yup. And that "reasonable estimate," in the first hours and days, was ten times the actual death toll, because most people in the towers got away without pausing to sign out.

You will never convince me

I don't doubt that.
