In this case I will say not Just equity is needed, human feelings too plays a great role in the way we define our equity, alot of things like this story happens on a daily basis, and you will be disappointed to see someone to actually know that a particular item he/she picked up somewhere else maybe due to carelessness of another, instead of returning it back all they think of its how to make gain out of it either by selling the item for money or using it, it's so unfortunate it's the world we find ourselves in.
