CA Sentencing Reforms Enabling Violent Criminals:  A man charged with murdering four and wounding two others with a machete last week had a criminal record that police say would have kept him behind bars prior to enactment of California's sentencing reforms.  Brian Day of KTLA reports that on August 8, gang member Zackary Castaneda was arrested for fatal machete stabbing two men at an apartment complex, the stabbing of a woman during the robbery of an insurance office, the random attack of a man at a gas station, the fatal stabbing of customer during a sandwich shop robbery and the fatal stabbing of a security guard at a convenience store.  Castaneda had multiple prior felony convictions going back to 2009, which, according to Garden Grove Police Chief Tom DeRe qualified him as a "violent individual who should have never been considered for early release based upon Assembly Bill 109."  That measure, called "Public Safety Realignment,"  prohibits prison sentences for repeat offenders designated by the state as "non-violent, non-serious, non sex offenders," requiring instead that they serve short sentences in county jails and release on probation.  In addition to committing numerous crimes, Castaneda had violated his probation seven times between 2016 and 2018.
