I want to know the answer to the following question:
What 2010 body found how difficult it is to accurately report the financial impact of infringement?
All the background I'm provided with is that "The GAO report explained that the sources – a Federal Bureau of Investigation (FBI) estimate, a Customs and Border Protection (CBP) press release and a Motor and Equipment Manufacturers Association estimate – "cannot be substantiated or traced back to an underlying data source or methodology."". Is that enough to answer the question?
Answer: no
