Because every state has their own way of doing it, and everybody thinks their method is best, The AP reports. Federal law says that all Amber Alerts are supposed to be based off a common set of guidelines, but the wire service found that nobody does -- the AP found states that don't even keep a record of past alerts.
Others will issue alerts in custody cases/family abductions, while others won't. One interesting point: Amber Alerts won't do much to stop abductees from being killed, experts say, because most kidnappers -- if they're going to kill the hostage -- do it within the first six hours. Which is how long it takes many alerts to be issued.
