Yes I am aware. But what does it mean? Well, it was performed by poor people that had no other means of nourishment but the act is usually connected with land use rights 
Are all people that caught poaching aware that they have trespassed on someone else's land?
I think that some don't really understand fully, like here in California there are people who say they did not realize they were poaching
no . they usually have some moral , which is peoples motivation
If you let them yes, just worrisome.
Well yes. It was against the rights of the top rulers and community leaders in ancient times
