This is the board for you if you wish to discuss or explore conspiracies of any kind, historical or current.
'Actual evidence from the affected floors' means .....just that.. Nothing more or less. (By the way they used none to spite admitting they could identify the placement of beams by their markings. Out of just over 200 pieces of the debris examined none were identified as being from the floors that initially failed)
And forensic analysis is does not use assumption at all. In fact good forensic analysis only deals in the known, quantifiable, facts as they are discovered.
If assumption were used in forensics our jails would be far more crowded than they are. Aren't the innocent fortunate?
