美国的爱护孩子的这套系统，确实值得中国学习，借鉴

美国的孩子的失踪案，很多是孩子自己主动离走。还有就是父母,情人分手争夺抚养权,发泄愤怒等等等等的,这一部分的人数很多.安全回归在这几类人群中是高比例的。 但是对于典型的失踪绑架案，如果是被陌生人绑架的，就也是很难回家了。

Key Findings
■ During the study year, there were an estimated 115
stereotypical kidnappings, defined as abductions perpetrated
by a stranger or slight acquaintance and
involving a child who was transported 50 or more
miles, detained overnight, held for ransom or with
the intent to keep the child permanently, or killed.
■ In 40 percent of stereotypical kidnappings, the child
was killed, and in another 4 percent, the child was
not recovered.
■ There were an estimated 58,200 child victims of nonfamily
abduction, defined more broadly to include
all nonfamily perpetrators (friends and acquaintances
as well as strangers) and crimes involving lesser
amounts of forced movement or detention in addition
to the more serious crimes entailed in stereotypical
kidnappings.
■ Fifty-seven percent of children abducted by a nonfamily
perpetrator were missing from caretakers for
at least 1 hour, and police were contacted to help
locate 21 percent of the abducted children.
■ Teenagers were by far the most frequent victims
of both stereotypical kidnappings and nonfamily
abductions.
■ Nearly half of all child victims of stereotypical kidnappings
and nonfamily abductions were sexually
assaulted by the perpetrator.
