I have been reading about this story of late, and the my impressions are that Brown was in the progress of doing some real investigative work on the these security/intelligence companies and their links with the US gov. And based on the severity of the charges against him, it seems that this is yet another case of DoJ going after people for political reason. The small amount of detail that was uncovered seems to be the tip of the iceberg. Are any other journalists looking into?
