I had no clue so many people shared in my belief that Snowden has done something great. I figured the media had corrupted most of the people into thinking he'd done something deplorable, because no one has been taking to the streets or to the polls or to the anything to demand changes based on his revelations.
Past generations would have, but that's not the case today. We think he's great. We just don't care to actually support him.
Historically, I feel like there was a notion that someone was "too popular to execute." But, even though the vast majority appear to support Snowden so much that they declare him POY, I don't think we'd do a thing if the US raided his home in Russia and put a bullet in him. We'd be mad, and we'd write blog posts about it, and maybe some people would DDoS attack a website or send a bunch of pizzas to John Kerry, but there would be no political turnover. There would be no justice on Snowden's behalf. At best, it would be like Guantanamo, where some new POTUS candidate promises change so we elect him, then does absolutely nothing. And we'd happily just not care.
