The entire episode stinks to high heaven. Justice is something that exists outside the borders of the United States. Never expect to find justice within the United States.
Most Americans are unaware of the extent to which the federal government owns the experts who can contradict its fairy tales. For example, no competent physicist can possibly believe the official story of the destruction of the three WTC buildings. But physics departments in US universities are heavily dependent on federal money. Any physicist who speaks his mind jeopardizes not only his own career but also the career of all of his colleagues. Physicist Steven Jones, who first pointed to the use of thermite in the destruction of the two towers had to agree to having his university buy out his tenure or his university was faced with losing all federal financing.
The same constraints operate in the private sector. High rise architects and structural engineers who express doubts about the official explanation of the collapse of three skyscrapers are viewed by potential clients as Muslim apologists and conspiracy kooks. The clients, of course, have no expert knowledge with which to assess the issue, but they are indoctrinated with ceaseless, endless, repetition that 9/11 was Osama bin Laden's attack on America. Their indoctrination makes them immune to facts.
The 9/11 lie has persisted for 13 years. Millions of Muslims have paid for this lie with their lives, the destruction of their families, and with their dislocation. Most Americans remain comfortable with the fact that their government has destroyed in whole or part seven countries based on a lie Washington told to cover up an inside job that launched the crazed neoconservatives' drive for Washington's World Empire.
