Update on Sony Investigation
As far as I can tell, there are (EDIT: at least) three scenarios:1. The NSA is competent, and has verified that NK is responsible.2. The NSA is competent, and is lying about whether NK is responsible.3.  The NSA is incompetent, and erroneously concluded that NK is responsible.Since we know that the NSA is filled with highly competent people (based on the quality of the people who periodically join the commercial world after a stint at the NSA) we can probably consider 1 or 2 the most likely explanation.Which do you believe, and why?  Unless there is strong evidence, 1 seems the most likely.  It's also the simplest explanation.Also, the reason I'm talking about the NSA even though the article is talking about the FBI is because this surely falls under their umbrella, and the NSA has the most powerful tools for verifying what happened.  Other agencies would seek answers from them, and the NSA's input would matter.  For example, one sentence starts, "As a result of our investigation, and in close collaboration with other U.S. government departments and agencies, ..."EDIT:  Could we focus on the question?  Which do you believe, and why?  Please feel free to add additional scenarios, but at least mention whether you believe them and why they're likely.
