This is a huge question where ethics definately comes into play. Would a person get caught if he shot a deer and had his youth tag it? Probably not. But the slob hunter that does this is not only violating the rules and the ethics, but he/she is teaching his/her youngster that it's OK to do the same. If I were to observe this happening, I would report it. But it would be his word against mine, unless the youth spoke up for what is right.
