This of course is why we have regulators, and the law courts to investigate, prosecute and where appropriate mete out justice....everywhere that is except in Wall Street and the City of London.
In this context please see specific recent public allegations that J P Morgan Chase has been fraudulently manipulating the price of Gold and Silver. This information was provided to the regulator, The Commodities Futures Trading Commission ("CFTC"), which deposed two separate whistleblowers from within J P Morgan, both of whom, at great risk to themselves and their careers, provided detailed and specific testimony regarding these criminal trading activities.
In particular oblige your representing politician, financial or investment advisor etc. to contact the CFTC and question them closely regarding the details of this case and their continued inaction on this matter.
Regrettably, it is only by standing up against these egregious, dishonest activities on the part of TBTF banks and complicit regulators, that we can ever rid ourselves of the cancer within the financial markets. Then true price discovery of the capitalist system would reassert itself over the rigged everything, crony capitalist system we have today.
The actions you and your company choose to take in this matter, will certainly influence the ultimate outcome.
