I'm pretty sure it doesn't have such a public registry. Some of the legal system in the US are very foreign to Swiss (and probably most continental Europeans for that matter), for example the way court proceedings are published and the accused can be named in the media before conviction. In almost every case, Swiss law enforcement and their corrective measures are meant to be that - corrective, not revengeful. This can sometimes lead to bad results (with quite a few people getting angry when crimes go with no or only light punishments), but overall most people probably think it's better to go too soft rather than too harsh, because the latter makes the government into a bully that everyone needs to fear, which people really don't want (and which a very active direct democracy hopefully somewhat protects against).
