That has got to be one of the stupidest things I have ever read. It is hard enough to hunt coyotes with a firearm, to get them close enough to bring them down with a boomerang taxes the imagination. If you dis manage by some stretch of the imagination to hit one with a boomerang, the odds of killing the animal is minimal. It is tantamount to throwing rocks. Whether or not you like an animal, a hunter should have the decency to make sure they impart a clean and painless kill and not make the animal suffer. Hunting them with a knife is even more ridiculous. I suspect you are not nor have you ever been a hunter.
