No it's not. The stubborn application of the law is called "rule of law" and it's the foundation of the political theory coming out of Enlightenment liberalism. Authoritarian governments are characterized by personalistic/charismatic rule, and the use of fiat/decree in the place of pre-existing legal standards.
Bradley Manning knowingly violated a long-standing law in the military code of justice that he was fully aware of since signing up. Applying the law to Manning is an example of rule of law not authoritarianism.
That is super stupid. You don't understand authoritarianism, then, citations of Wikipedia aside. You do a disservice to the actual victims of authoritarianism.
EDIT: Look at the downvoting.. and this is nice compared to what I wrote at first. Since I'm already -3, I'll remove the politeness filters and say that this comment is idiotic. Stubborn application of the law is authoritarianism? How is that not the dumbest thing written on the internet today. Perhaps I'm the stupid one for believing that WORDS have MEANINGS beyond what is convenient at the moment. It's like people saying that food stamps are socialism. It's not opinion, it's INCORRECT.
All of my examples are universally considered extremely immoral. However, there are also some countries that are mostly authoritarian, but are arguably not immoral (some middle eastern sultanates come to mind). There is an enormous body of though on the morality of laws. This starts in Greek time with Plato and The Republic, and has had contributions from Aquinas, Hobbes, and more recently MLK. A non-authoritarian state can easily pass immoral laws, too.
Finally, the degree of enforcement of law is a concept which I consider separate from the system of government and the particular laws of the society.
So my objection is that the post commingled three separate ideas: the origin of law within a society, the morality of law, and the rigor of law enforcement. I think the commingling was incorrect. I think some of this is so obvious that not recognizing it can be fairly characterized as stupid. Hope that I hope that clarifies things.
To offer my opinion, the US is not close to being an authoritarian state. However, it has some immoral laws. That can be rectified via a democratic process. I think the enforcement of those laws in this case was actually fairly lax, because he clearly committed crimes and it would not have been difficult to have made a case for treason which would have been eligible for capital punishment, as another commenter noted.
So the question shouldn't be "why hasn't the democratic process rectified bad laws", but rather "is there a better process than the democratic process for rectifying bad laws"? I know this sounds like Churchill, but it's also a bit of Gödel if you think about it.
Funny. That is exactly the point this "retarded" commment is making.
It seems people are quick to point out that Manning broke some rules, but are too narrow-minded to look up and see the big picture. Manning undeniably made a service to the greater good, which is the good of his country. Whether he broke some rules internal to his organization should not even have come into play in this trial.
