Funny this comes up now, I actually just saw a video on youtube recently of a guy dinging a deer from a helicopter. It wasn't in the US, and I can't say it seemed particularly sporting.
Given the number of big-city media outlets that employ dedicated outdoorsmen as op-ed reporters (*crickets*), I think the first commenter to the article raises a good point. While I'd love the opportunity to go hog hunting, I don't really have that chance, because (thus far) it seems like the state DNRs and their policies have prevented feral pigs from becoming the nuisance they are further south. Despite my lack of experience, I have a sense that hogs (and coyotes) have always been regarded with some disdain, and many public and private entities have encouraged their culling. I am not suggesting we condone helicopter hunting, but there's probably a flip side of the coin being underrepresented here. I do think the protesting groups are abusing an opportunity to get the uninformed riled up. If they love hogs and yotes so much, how about spending this time to relocate them to a place where they can't be hunted. They can try their own back yard first and let us know how that goes.
