Just like i said you have a big trouble in reading.
Some 200 technical experts—including about 85 career NIST experts and 125 leading experts from the private sector and academia—
reviewed tens of thousands of documents, interviewed more than 1,000 people,
reviewed 7,000 segments of video footage and 7,000 photographs, analyzed 236 pieces of steel from the wreckage, performed laboratory tests and sophisticated computer simulations of the sequence of events that occurred from the moment the aircraft struck the towers until they began to collapse
they get an instruction.
But those 200 are not the investigation team.
So again for the third time, u see here the investigation team, thats make the decision what happened with the three collapses

If i hire you as a detective to spy on the friends of my girlfriend.
Than you are not the one to make the decision if i can trust my girlfriend.
You only have to report what the activities are of the friends of my girlfriend.
And i will hire some one else to spy on my girlfriend.
And another to act as someone who is trying to get my girl.
And i am the investigation team thats makes decision based on the results, if my girlfriend is reliable or not.
