The Evidence:

In a systematic review, a Community Guide expert panel reviewed seven studies evaluating the impact of six laws allowing juvenile transfer. McGowan A, Hahn R, Liberman A, et al. Effects on violence of laws and policies facilitating the transfer of juveniles from the juvenile justice system to the adult justice system: a systematic review. Am J Prev Med 2007;32(4S):S7–S28. Across the studies, the reviewers observed an overall negative effect. Notably, there was a 34 percent median increase in recidivism among youths processed though adult systems compared to those retained in the juvenile courts. In addition, transfer of youths led to an increase in pretrial violence, victimization and violence in adult facilities, and elevated suicide rates among the incarcerated youths. According to the expert panel, there was not enough evidence to determine the true effect of waiver as a deterrent.

The Evidence:

In a systematic review, Zaza et al. reviewed nine studies that evaluated the effectiveness of child safety seat laws in reducing rates of childhood motor-vehicle injuries. Zaza S, et al. Reviews of evidence regarding interventions to increase use of child safety seats. Am J Prev Med. 2001;21(4S):31-47. The underlying studies focused on laws that were passed in every state in the United States between the years 1978 and 1986. The reviewers found a 35 percent median reduction in fatal childhood injuries and 17.3 percent reduction in overall motor-vehicle child injuries following the introduction and enforcement of child safety seat laws. The effects of additional requirements in particular states (for example, requiring a particular seating position or providing for harsher penalties) could not be determined from the available studies. The reviewers also identified a 13 percent increase in the use of child safety seat use subsequent to the adoption of child safety seat laws.
