Poor editing
Mr. Nguyen, you deserve all of the abuse that can be generated by this article. If the point of the original article was to inform people then this totally fails. You have insulted every rational person that reads this by not providing the context and rational for the ratings. Risk analysis is always a product of the opinions (reasable, informed or otherwise) of the analyst. Without that information this is a waste of time and space.
If you argue that you simply posted what was given to you or even worse edited it to remove the references then you should be fired immediately.
