Pennsylvania echoes all three of the responses listed so far. Related to criteria: we also adhere to DOJ criteria. Our requests must also come from Law Enforcement.
Echoing Montana, we train Child Service Workers as often as we can. Often times here, these issues are created by half measures taken by courts and child services. Finally, when the party(s) disobey, they want the AMBER. Criteria rules the day.
Finally, to Delaware’s point, we have a step down alert (Missing Endangered Person Advisory) that could cover circumstances related to the child being in danger but not due to an abduction.
