Joseph,
1. Once again you demonstrate lack of Torah knowledge. The secular authorities have the right and obligation to punish people according to their own standards of proof (see CM 2). Rav Moshe even wrote in a letter to then NY Gov. Hugh Carey in support of the death penalty (IM CM 2:68). The reason, as I understand it, is that the bet din’s job is to enable the sinner to atone whereas the secular court’s job is to maintain public order.
2. Even in Halacha there is the concept of a “kol shelo posek” or “kol ha’am meranninim”.
