Are you worried about the torture or the stolen Bitcoin?
Jungle justice is usually frequent because the mobs are not punished and due to slow justice system.
I have observed that "leaders" of the countries where this is frequent don't speak against it. I think if they speak against it and act people would be more careful next time.  But there is a culture of silence while the lawlessness persist. Could be due to fear of the people or they are tactically encouraging it
