Bumper Stickers

So I was driving around (actually to my vikes) and I saw a bumper sticker and it said: Free North Korean refuges in China. I was like ok, cool spreading the news and stuff. And under that In smaller less noticeable letters it said: Before the Beijing Olympics. I actually got kinda upset about this, because shouldn't we "free" them just because people are going to see China because of the Olympics, we should do it because its right. Unless I misunderstood the bumper sticker, which is very possible. I was under the assumption that the refuges were free in China, or at least free of the North Korea. So what am I missing here? Anyways, I just didn't know that I would get that upset over a bumper sticker.
