I agree with Texas Bryan 100% on carrying a side arm while hunting. Especially if you are hunting dangerous game. I cannot believe none of those hunters were hurt when the lion charged and attacked? Scary video.
I also agree with Kid Shellen, if you are not going to eat it, why kill it?
I think one of the last shots before leaping at the guide did some real damage. I replayed it, and the way the lion's body reacted looked like he was hit as he was going in for the bite. His body almost looked like it was slammed, with the upper part stopping and the lower part continuing a bit under the upper part. That can't be faked. I would think. He missed the guide mostly, and had his mouth wide open for a killing bite as he passed the guide. The shot distracted him enough to miss, possibly reflexive?
Were I the guide, I would have burned my shorts, there would be no way of ever getting them clean.
2how, I understand the "canned hunt" hostility, but these preserves are generally very large. I stayed on an elk hunting preserve in SD some years back that was 11,000 acres. For the geographically challenged (Haz? ?

) that is roughly 15 square miles. Yes, it is surrounded by a fence, but that only limits animals at the fringe, not in the middle. If this were a case of sitting at your computer, and pressing a key to fire a gun, I would be with you. These guys, however, are on foot in amongst the lions. More than I would ever do.
I too was troubled by the large number of shots being whipped around
