Vanishing Violence

About the series
Violent crime by youths in California plummeted over the past two decades and arrests of juveniles for violent felonies fell 68 percent. In human terms, a Chronicle analysis shows, the downward trend in violent crime has resulted in 4,700 fewer juveniles slain in California during the past 2½ decades; 150,000 fewer arrests for rapes, assaults and other violent crimes that didn’t happen; and hundreds of thousands of youths not booked into juvenile hall. San Francisco Chief Juvenile Probation Officer Allen Nance began working with youth offenders in the late 1980s and witnessed the crime wave.
