The "Three Strikes Law" is a legal policy that mandates harsher sentences for individuals convicted of multiple serious crimes. Under this law, if a person is convicted of three or more serious offenses, they may face significantly longer prison terms, often life sentences. This law aims to deter repeat offenders and enhance public safety. Originally implemented in the 1990s in states like California, the law has sparked debate over its effectiveness and fairness. Critics argue that it can lead to excessively harsh penalties for non-violent crimes, while supporters believe it helps reduce crime rates by incapacitating habitual offenders.
