The only altercation we have witnessed was between a game warden and a black bear. It was in a provincial park that was only 1/3 full, after pulling in and beginning to set up I noticed a black bear was expertly rummaging through our neighbors tent. I got up on the roof of our camper and began filming, when a green truck towing a bear can pulled into the site on the other side of us. Officer Rookie saw me up on the roof with my video camera and advised me that there was a dangerous bear in the area, I kindly pointed out the bear next to us and asked him if that was the bear he was looking for? Officer rookie looked around and since it was empty in the area if I would mind if he destroyed the bear as it had a confrontation with several other campers in the last few days. I said not a problem, Rookie got out his rifle slowly got close to the bear as is was enjoying a tub of Parkay. Dude sites in the bear and "CLICK" , forget to chamber a round. Yogi hears the click, and makes like a race horse with Rookie in full pursuit. Bear stops to scratch himself , double tap....no more picknic baskets for Yogi.
In my 40 years of camping, other than a few obnoxious buffoons no issues.
