As Shelley has pointed out, Stinky Journalism has done a take-down on the Hogzilla II photos (see here and here) and has concluded that the hog was not as large as claimed. Not all of that debunking is, it appear, correct, so you might also want to see this debunking which claims that the photos were manipulated digitally as well as through use of perspective (see in particular figure 3, reproduced above in smaller form).
Predictably, the article resulted in a whole bunch of comments by folks defending the boy-hunter ("Let the boy have is momeny of glory"). My favorite has got to be:
I BELIEVE THIS KID SHOT THE PIG AND ALL YOU PEOPLE ARE JUST JEALOUSE ASS HOLES WHO ARE MAD BECAUSE YOU WERE RAISED HIPPIES WHO CAN’T HUNT!!!
Update: Turns out the hog was a farm-raised pet, not a feral behemoth and “[t]he big boar was hunted inside a large, low-fence enclosure and fired upon 16 times by Stone, who struck the animal nearly a half-dozen times during the three-hour hunt.”
