I don't really have a problem with the video. They could have dispatched it a little sooner, put it out of it's misery. But look, these Feral Hogs, are no different than the rampant Gophers that are present on the Prairies. They are a pest. Who doesn't like to see a video of Gophers exploding from a 22-250 using V-Max's at 100 yards.
Like I have always stated, Ethics has nothing to do with a legal hunt. Ethics is something that we all have to chose individually, and you can't force that on to someone else. If you don't like what you saw, well, to bad. It seems like it was a legal hunt, I feel they could have dispatched the animal a little quicker, but you know what, those guys will probably sit down, have a couple of beers, while the Pig is roasting over a fire, and have a story to tell to boot, and some of them might feel bad, and do things differently next time.
