The story of Polly Klaas’ murder by a man with a history of violence galvanized California voters into passing the state’s three-strikes-and-you’re-out law in 1994. Two dozen states and the federal government have now adopted similar laws. Still, only in California can conviction on any third felony put someone behind bars for life. That singularity points to what is wrong with the California law, despite its emotionally wrenching origins.
Eleven years after Polly was snatched from her upstairs bedroom and murdered, voters are troubled by other stories--about the Army veteran who stole $153 worth of videotapes or the father who pinched a box of diapers for his baby, both now in prison for life, and about the $31,000 that taxpayers pony up every year to house such individuals. Those tales should push voters to pass Proposition 66, correcting a gross injustice while reserving the harshest punishment for those who commit the worst crimes.

A. people who go on strike three times in prison will be out of prison for good
B. people who are beaten up three times in prison will be freed from prison
C. people who are convicted of three felonies may end up facing life in prison
D. people who finally strike sympathy into the public’s hearts will be freed
