North Korean Olympic Athletes

With all the talk of how athletes from North Korea are rewarded or punished for their performance at the Olympics, I have to wonder how much is true and how much is rumor? No doubt the country is strange and keeps their people on a "tight leash," but labor camps for losers? The "revered leader," Kim Jong-un looks like a puss--but then a weakling in power is often the worst kind of bully.
