Two suggested topics:
1) Other than the NIST reports explaination of what brought down the towers upon their examination of the beams, has anyone with the balls enough to imagine demolition might be the cause done a forensic analysis on the central core beams for evidence of explosive granular penetration? As in all things reported by any part of the government that leave room for doubt, the analysis of the data must be reviewed independently. What's to stop someone in the vacinity of the hangar at JFK airport from doing a thorough forensic analysis on the tons of beams stored there? My questioning all things government is based more on the human nature of avoiding even suspecting the worst possible exploitation of oneself by your last refuge for succor, so that any thing smacking of that horror is shoved down immediately and mixed in with the bile of the grief, than based on any intuition that a vast network of conspirators have falsified things under orders from the idiot son in the capitol of the United Stetsons.
2) Just a hunch that if some of the clean up crew in the weeks after the collapse were to be interviewed by 911 truth seekers in the neighborhood there may emerge a whole new proof of explosions versus collapse. I don't know what oaths they had to take to get the job or if they did at all, but I have learned they are really pissed at the betrayal of the government all the way from FEMAs inconsiderate, hurriedly declaring the area safe to the total contempt with which the government five years on continues to regard their pleas for medical assistance for the asbestosis and related diseases which may end up killing three times more people than the tragedy itself. If any group since 9/11/01 have reached the capability to suspect the government of the worst and who can recall evidences which were unexplainable to them without an inside job as a possibility, it is these people.
