I think he killed a defenseless pen raised deer. Can't imagine being too excited over killing a helpless pet that has had it's instincts dulled by living in a cage.
Sad story.
Or kinda like killing a fawn, young deer. They know 0 about hunters. So if shooting a defenseless deer is not very sporting then shooting fawns is very sporting. If we use the above logic. I for one hate pinned deer farms, but this deer was in the wild and he shot it. So who am I to Judge, I could care less if people shoot fawns it is choice of the hunter. I am tired of people ripping on others for what they shoot!!
