I understand your point. But I think the problem actually arises long before strike number three. In most cases, it's ONE strike and you're out as far as "bad social credit score" goes. It's just going to be VERY difficult for you to secure employment, or even decent housing, with that conviction on your record.

Just one of the hard realities of the legal system.

Originally, the 3 strikes laws were to be used only against violent felonies. I'm not sure how they were able to include non violent offenses to the list.

Easy. Find one example of someone who stole something three times, then later murdered someone. Scare people with this fact. Make up a theory about how larceny is a gateway to violence.

This is, exactly, how the immigration debate is being held in DC. One undocumented shot and killed a citizen by accident, and now we're supposed to kick all immigrants out. Visceral emotion is a great tool to optimize society for corner cases.

I am not sure I follow your question as it is very open ended. Are you asking if I am in favor of incarcerating criminals who continually commit violent felonies?
