The goal of the plan is fairly simple: use basic broadcasting technology to beat the clock in abduction cases. Nearly three-quarters of children killed in cases of stranger abduction are murdered within the first three hours, according to U.S. Department of Justice statistics. The Wiki entry appears to be incorrect, but often repeated (and every so often, it is pointed out that the media got it mangled):
Fast action is necessary since, 1) there is typically
over a two hour delay in making the initial missing
child report (60%), and 2)
the vast majority (74%) of
the abducted children who are murdered are dead
within three hours of the abduction. Because of these
critical time features, it is important to respond quickly
with a neighborhood canvass and search of the area.
