Since two sex offenders were charged with killing four women while under state and federal watch, California has changed how it supervises such parolees, increasing scrutiny of some and relaxing the monitoring of others, reports the Los Angeles Times. The newspaper’s analysis of state data shows that the number of parole agents with caseloads exceeding state limits has increased under the new system, further stretching California’s already strained ability to oversee freed sex offenders. The new regimen, which ties parolees’ supervision to risk-assessment tools, therapy and their own behavior, “will let us achieve higher levels of public safety,” said Douglas Eckenrod, who runs the state’s sex offender monitoring program.
