But we've already allowed it to happen. He's been in jail for years now. For something he may or may not have done. He's on the verge of being deported to the US, where he will most likely be imprisoned for journalism. Something he shouldn't have had to think about. If we wouldn't have allowed this to happen in the first place, he could have stand trial for the other things he's been accused of.
So it's already happened. It's why Snowden is in Russia, instead of living his life in the US.
