Criteria for Activating an AMBER Alert
Law enforcement agencies are required to ensure that the following conditions are met before activating an AMBER Alert:
The victim is under the age of 18
Police have reasonable grounds to believe that the victim has been abducted
Police have reasonable grounds to believe the victim is in imminent danger
Police have obtained enough description information about the victim, abductor or an involved vehicle
Police believe that the alert can be issued in a time frame that would provide a reasonable expectation that the child could be returned or the abductor could be apprehended.
If ALL of the above criteria are NOT met, an AMBER Alert will NOT be activated.
Seems like there's a whole lot of reasons why an Amber might never actually be called. Even though these kids weren't gone for more than 8 hours, I guess some press is still better than none.
