Multiple errors are exhibited in this video exchange between hiker and bear. First, the hiker keeps backing away, which gives the bear the idea he is retreating (which of course he is). He should have stood his ground and actually advanced while yelling and waving his walking stick, and he should have done that while he was on the high ground at the beginning of the film. And forget filming this, he clearly had bigger, furrier problems to deal with. The idea is to convince the bear that you are not prey, and will fight. That should have put an end to the encounter. Further, we assume this guy got away in the end, and that the camera wasn't found later by a search party after he had gone missing for a week!
