Actually, most of the social "countermeasures" were adopted after high-profile single incidents in the 1990s (perhaps largely because the larger 1960s-1980s crime wave that had been the pretext for expanding government powers in the law enforcement arena previously was ending, and a new pretext was needed) and later, when the overall rate of incidents had been dropping for decades (since, IIRC, the 1950s or 1960s), but media attention to them -- and hence public perception of the prevalence of incidents -- had, at the same time, been increasing.

AFAIK, there is little-to-no evidence that any of the "countermeasures" have had any significant effect on the prevalence of child abduction/predation.
