Since you don't seem to be aware of very basic information about who has signed their name to a petition calling for a new investigation, you will likewise have no clue what campaigns truth supporters have already funded and are continuing to fund. 9/11 truth isn't a private club that asks for membership dues. It's not a single group. Your comment here is misinformed and irrelevant.
There are 1,460 who have publicly stated their disagreement with the official story. So, yes, there are many, many, professionals in these fields who are asking for a realistic explanation.
I might be tardy to the party on this one, but I think we need to address this point again. By your own admission, it is incorrect to refer to AE911 as a cohesive group. Indeed, they have no group or incorporated structure at all.
I belong to a relatively small professional society of about 400 dues paying members. We have yearly elections for officer positions, we have a constitution, we have a mission statement and we have a yearly business meeting where society direction is determined through consensus and referendum. Because of all this organization, our society has provided 8 partial scholarships for students studying chemistry and materials science, and we've supported 4 international meetings, providing travel support to dozens of researchers from around the world. Our members publish about 50 papers per year (with the members being the first author) in peer reviewed, high impact factor journals.
In short, we actually do stuff. We have goals, and we accomplish them.
By comparison AE911 has never held elections. They have no documents of incorporation, no bylaws and no input from membership. None of the members, outside of a handful of charlatans, have ever produced a document stating their scientific conclusions regarding 9/11. This, from an organization 3 times larger than mine. If AE911 is a professional society, then its strength can be measured by contributed research papers. If AE911 is an advocacy group, then success could be measured by what proportion of the members are involved in advocacy. If AE911 is a lobbying group, then its importance could be judged by how much legislative and executive action it has generated.
Of course, if AE911 is an advocacy group, then the qualifications of the members matter very little and the extent of their public advocacy is limited to a tiny proportion of the group. If AE911 is a lobbying group, it's incredibly ineffective. If AE911 is a professional society, it is a dismal failure.
You're right, ergo. 911 Truth is not a private club. But it is a disorganized, loose confederation of idiots that has utterly failed at everything. Organization is the 0th step in getting something done. It is silly to pretend that the lack of organization in the Truth movement is anything but its greatest weakness. You need bylaws, you need officers, you need volunteers. Richard Gage knows this. He's a member of AIA, but he's also not an idiot. Gage knows that there is no consensus within the Truth movement, and any attempt at organization would fracture and destroy the movement. What works for my society and for the AIA won't work for the Truth movement, can you figure out why?
How should we treat the total number of members of a loosely collected internet petition? It is a number, and nothing more.
