I think some people do rehabilitate successfully and from an economic standpoint, I think that all the reprieves granted cost us a fortune. I also believe in choice for abortion, another related issue. Because I live in the real world. Look, you probably don't run into people who have multiple convictions. But I sure wouldn't want to.
