Some of us don't already know everything. Learning is fun when it's a topic of interest.I have to wonder about people who are taking pictures of many wound channels and entrance/exit of many animals. It's almost like they are surprised or have something to prove. I bet you are in the minority if you've ever taken a picture of an entrance and exit wound.
Even more strange is asking someone to try to prove what's better by similar pictures. The truth is we aren't the animal in the picture and don't know what is better from the animal perspective. There is really no way to know, but video up close would be better if not even more graphic.
