I do think that the rule should be that if anyone threatens death on this site, the police should get involved. I don't care if it's a child making the threat, it's like abuse cases, better to report and say sorry later, than to not report and watch the child get beaten to death. If you make the threat, be prepared to face the consequences. I even think that should be one of the rules, so that posters are aware that we do take death threats seriously.
Not that long ago we had a poster that came here, admitted to luring a very young teen to his neck of the woods, bought her a plane ticket, posted here that he planned to have sex with her, had booked a hotel room. That man is now in jail, his posts on this site were emailed to the authorities. He was caught at the airport, with condoms and alcohol on his person. The girl is safe. She was 13, if I remember correctly.
Sometimes you have to take the written word at face value. If someone threatens, it's better to report and be wrong then to do nothing and they make good on their threats.
