It's popular these days to say, "Hey, if it's legal, go for it," which implicitly embraces anything the law does not expressly forbid. But hold on just one durn minute: What's legal is not always ethical or fair. It is legal in Texas, as I understand it, for rank amateurs and, I'll add, nincompoops to shoot pigs from helicopters, maiming fifteen for every one they kill--for fun (see the video below). That's legal. It is neither ethical nor fair chase.
