> As soon as they're out of prison they're once more a full civilian. Which is not what's happening. Why do those punishments on top of serving jail time or community service exist?
I'll be honest, I don't know enough about the topic to really answer this. Some quick Googling suggest that this is what happens, though. According to this page, [0] many states restore your voting rights automatically after your sentence is completed, and some very liberal ones even allow for voting in prison (which in my opinion is really stupid).
> Don't you think rehabilitation means that a person fully integrates within society, including the benefits that provides?
I don't think that rehabilitation happens instantly, so it makes sense that voting rights be restored after a period of years. Felons need to prove that they can live in the real world again before they can vote to change it.
