One thing that makes me doubt the whole claim is that the "secret team" wasn't able to bail out Long Term Capital Management in secret. That required meetings that were quickly made public, and appeared to be quite abnormal. Yet if a PPT exists that is exactly the scenario that they would act it.
I believe that GATA has ammassed quite a bit of evidence to support the idea that a number of Reserve Banks, led by the Fed, and in conjunction with major investmant banks especially Goldman's has had a big hand in manipulating the gold market through various accounting tricks and a tricky leasing scheme.
It's just a coincidence that both Clinton and now Bush appointed former Goldman heads to be their Sec. of the Treasury. I'm sure, really.
I am not sure if it is even a question of whether the Plunge Protection Team exsits. The Washington Post rported on them http://www.washingtonpost.com/wp-srv/business/longterm/blackm/plunge.htm
