What is the purpose of a "three strike law"?

The purpose of a "three strike law" is to impose harsher sentences on individuals who have been convicted of multiple felonies, specifically after their third felony conviction. This legislative approach aims to deter repeat offenders by establishing mandatory minimum sentences, often leading to life sentences after the third conviction. The "three strike law" was designed in part to address concerns about violent crime and recidivism, reflecting a policy decision that emphasizes punishment over rehabilitation for those who have demonstrated a pattern of criminal behavior.

In this context, the law is based on the belief that habitual offenders pose a greater risk to public safety, and thus, more severe penalties are warranted for those who repeatedly engage in criminal activity. This law has been controversial, as critics argue it can lead to excessively harsh sentences for non-violent offenses and highlights issues around the effectiveness of deterrence versus rehabilitation. However, the core function remains solidly focused on escalating legal consequences for repeated criminal actions.
