The three-strikes law was created in 1993 in California after the murder of Polly Klaas. It imposes life sentences for criminals convicted of three felonies, with the third being a serious or violent crime. While it aims to keep repeat offenders incarcerated, it has significantly increased prison populations and costs. Critics argue it punishes some non-violent offenders excessively. Organizations like F.A.C.T.S. are working to amend the law to make it more tailored and fair.
