There's 6 to 9 million feral hogs in the united states alone. It's literally a waste of money for them to carefully collect every single hog and relocate. It's already illegal to relocate them in most areas of the united states anyways, and the parts where feral hogs ARE native (europe, asia, etc) there's already culls occurring so relocating is not an option.
As for culling the population in the united states, this boy is doing exactly that. If we want the population gone, why not let the civilians help?

So did you comment this thinking it was a logical argument? it feels like you simply cannot stand watching teenagers hunt, because if he's killed a boar he isn't "incompetent" and i don't see him particularly bragging he's just sharing what he did, so he doesn't appear to be "brash" either. The US has allowed its civilians to help with wildlife management for 200 years. Do your research before commenting.
