'Struck by Justice:' Polly Klaas murder led to harsher sentences. Is that the answer to crime?

SAN FRANCISCO (KGO) -- This month, California marks 30 years since the adoption of the Three Strikes and You're Out Law.

POLLY KLAAS CASE: Here's how 1993 Bay Area murder of 12-year-old transformed criminal justice system

It was enacted a few months after the murder of Polly Klaas in Petaluma, a 12-year-old girl who was kidnapped and killed by Richard Allen Davis, an intruder with a long criminal record who has just been released early from prison a few months earlier.

Outrage over the crime led to the swift passage of the Three Strikes Law, which doubled an offender's sentence for a second felony conviction and required mandatory prison sentences of 25 years to life for a third conviction.

It was the start of tough on crime policies that swept across the nation and led to mass incarceration.

In 1996, a newborn was found brutally beaten in his house. The suspect -- a 6-year-old boy. ABC7's Lyanne Melendez searched for both children, now adults, to find out how a horrific event changed their lives in "Unthinkable."

At the national level, President Bill Clinton signed the 1994 Crime Bill, which allocated $10 billion for prisons, eliminated higher education grants for inmates, gave incentives to states to implement mandatory sentencing and imposed life sentences for people convicted of certain felonies.

As criminal justice reform gained momentum in the last decade, some of the more punitive aspects of the Three Strikes Law have been rolled back.

Ten years ago, California voters approved Proposition 47, which made some non-violent property crimes misdemeanors.

But now, as car break-ins and retail store theft rise, critics of criminal justice reform are calling for a return to harsher sentencing and pushing back on prosecutors who back restorative justice over longer prison sentences.
