New New Jersey law on child abuse

On the question of offering protection for vulnerable children, the New Jersy Assembly have taken a different approach to the UK government, which is building a database on all children. The assembly, according to Larry Lessig, are passing a law to remove immunity from negligence in hiring in all cases involving abuse. This law provides those hiring people to work with children an incentive to do comprehensive checks to ensure those people are suitable to do so. Placing the responsibity and the resources in the hands of those organisations who can and actually do support vulnerable kids makes sense. Does spending money, which could otherwise be put into front line services, on a huge database make similar sense?
