I will admit the way Mr. Snowden escaped after divulging so much about the invasion of the privacy of American citizens (the Prism scandal), appears to be very suspicious. And knowing that he went to countries that are not too friendly to the USA. doesn't help make him look like a hero. In fact, it makes it more convincing that he has turned out to be a traitor to his country.
Still, I would not be in a hurry to put a tag on him at this time for having done what he did. Although it looks bad there are other things to consider. There could be something else involved in this. In war and espionage there are a lot of scenarios that could be followed to obtain information on another country to help ensure the security of a nation (in this case security for the USA). Eventually the truth might or might not come out. We will just have to wait and see.
The reason my rant is on this is because accusing a person of being a traitor to his country is very serious. And how suspicious it looked might be legitimate, but it is too early to make pronouncements. I don’t want to say any more on this subject.
