I'm not going to throw stones at the kid, firearm choice, techniques, etc.
My question stems from doubts that the animal was as big as they say. Looking over the site, all the pictures appear to have been taken from a position of forced perspective. The humans are always located behind the animal and the focal depth of the pictures make me think that someone is pulling something. Then they talk about it being weighed on a certified scale, but the owner of the scale wasn't there to witness the weigh-in.
Maybe I'm just too skeptical. If it was me, I'd have called in the local extension agent, someone from the DNR, local news crews or anyone else I could think of to verify the size of the monster. I'd of had the pope bless the scales if that's what it took, but I'd have solid evidence that the beast was the size I was saying it was.
