Most of the people I have read or heard advocate for "more effective handling of crime" are much bigger on the severity of the sentence, though I don't deny that many will mention both. The "N strikes and you're out" angle, for example, is all about the severity of the sentence once you reach N.

New HN commenter "smeeger" whose subthread we are in seems close to favoring violence as punishment for relatively minor crimes, for example.

Still, yes, things that significantly increased the likelihood of being caught and punished do seem like a good idea, and do not require sentencing being changed.
