I never walk with a shell chambered and I'm pretty disciplined about that. I hunt the majority of my time side by side with my wife so always having a person near you means you have to be religious about that rule.For Part II of the question, did you unload your rifle before it was pointed in the general direction of their camp during the pic?
This is what would concern me the most. I don't know that it's necessarily an ethics question, though. If it's legal and safe and you want the animal go for it. Reading the description, it doesn't sound like something I would prefer to do, but my preferences are known to change based on circumstances. For me, the fact that sometimes I would, sometimes I wouldn't means it's not an ethical dilemna.I don't particularly want to hunt near other peoples' camps anyway, but having an angry & armed person come out of the tent I thought was empty insisting I "shot up their camp" is a situation I especially don't want to deal with.
That's funny.The first year a friend of mine ever went bow hunting he had his camp set up in a popular hunting area. He was solo but got to know the guys who were camping a couple of hundred yards up the road. Then one evening he was walking up the road to get to where he was planning on hunting. When he got to the neighboring camp everyone was gone out hunting but there was a nice three point buck standing there eating their soap. So he shot it. Everyone got a good laugh and it tasted just as good as any other deer.
