Det har de ju gjort - de har både förklarat varför de inte testade om sprängmedel eller någon form av termit användes och de har även förklarat varför det inte skulle vara meningsfullt att testa om termit användes..
22. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues?
NIST did not test for the residue of these compounds in the steel.
The responses to previous questions demonstrate why NIST concluded that there were no explosives or controlled demolition involved in the collapses of the WTC towers.
As for thermite (a mixture of powdered or granular aluminum metal and powdered iron oxide that burns at extremely high temperatures when ignited), it burns slowly relative to explosive materials and would require several minutes in contact with a massive steel section to heat it to a temperature that would result in substantial weakening. Separate from the WTC towers investigation, NIST researchers estimated that at least 0.13 pounds of thermite would be required to heat each pound of a steel section to approximately 700 degrees Celsius (the temperature at which steel weakens substantially). Therefore, while a thermite reaction can cut through large steel columns, many thousands of pounds of thermite would need to have been placed inconspicuously ahead of time, remotely ignited, and somehow held in direct contact with the surface of hundreds of massive structural components to weaken the building. This makes it an unlikely substance for achieving a controlled demolition.
Analysis of the WTC steel for the elements in thermite/thermate would not necessarily have been conclusive. The metal compounds also would have been present in the construction materials making up the WTC towers, and sulfur is present in the gypsum wallboard that was prevalent in the interior partitions.

Om man inte tycker det är viktigt att leva som man lär så kan man förstås resonera så som du gör i denna fråga...
Den ursprungliga frågan var ju varför inte Jones et al tillåter att oberoende aktörer får testa deras rasrester. Oavsett om just Jones et al har uppmanat NIST att göra det som det amerikanska folket gav dem i uppdrag att göra, så torde de knappast ha missat sanningsrörelsen krav på det.
Att i det läget attackera Jones et al är helt befängt. Och, även om Jones et al låter tredje part testa deras rester så är det ju ändå ingen s.k. skeptiker (reclaim the word!) som kommer att godkänna chain of custody.

Fast det skulle förstås inte lösa någonting alls - precis som du säger att skeptiker skulle ifrågasätta hanteringen av Harrits prover så skulle det gå att ifrågasätta om NIST provat "rätt" stålbitar. Och - som NIST själva skriver - förekomst av samma restämnen som termit ger skulle inte på något sätt bevisa att termit användes..
Det enda sättet att en gång för alla lösa det här är att NIST gör de tester de var satta att göra för snart 15 år sedan. Genuint oberoende kontroller och full transparens i samtliga led för att helt utesluta mygel och ministerstyre.

Hur mycket är det?
Kostar? En promille av en promille av vad underlåtenheten att göra testerna har kostat hittills.
