I'm not trying to be difficult here, but I've seen video of other lion hunts taken in less settled areas which showed nice solitary male lions exhibiting similar behavior, when they are first encountered. Large predators come into farms and ranches regularly in rural North America, so why is it not possible that is what occurred in this video? I think it is possible the lion had been observed for a day or two, then a decision was made to take him. Perhaps he had taken an antelope nearby or even some stock, and that would explain why he hadn't left the area.
