I don't even believe this guy was there to hunt deer.
I suspect he just wanted to have himself a little shooting spree. What better place than out in the woods, picking off some hunters.
This makes it more of a sport than simply walking into the post office, or MacDonalds. Definitely not a "hunting incident", as it is being portrayed.
I agree...I also don't think the guy was there to hunt - he was there for an ambush.
