It may sound hypocritical for an American to oppose concentration camps in North Korea based on America's prison-happy justice system, but please keep two thing

It may sound hypocritical for an American to oppose concentration camps in North Korea based on America's prison-happy justice system, but please keep two things in mind: 1. It is only hypocritical for the speaker if he supports America's prison-happy justice system. If he opposes it, or has misgivings, or is undecided, it is not hypocritical to oppose North Korea. 2. Even if it is hypocrisy, that doesn't diminish his words in any way, just your personal opinion of him. If his criticism is invalid, it can be disputed directly. If his criticism is valid, he could be as flawed and terrible a human being as we can imagine and his criticism would still be valid. #2 is the key point. Arguing that his words are hypocritical is a kind of Ad Hominem Abuse, something generally discouraged on HN as a kind of intellectual laziness, a rhetorical appeal to emotion rather than an analysis of the argument being debated.
