Besides for executing minors/mentally handicapped, the US does all those things. Torture (waterboarding), hold prisoners without trial/charge (Guantanamo Bay), allow their leaders to execute citizens summarily (drone strikes), incarcerate people at a high rate for benefit of state sponsored corporations (drug war - privatized jails). I'm not arguing politics - I don't think HN is the place for it, but you should evaluate your perspective and how it might be changing how you view the world.
