Hohawaiian,
I'll stick with what I said. Lining is a more selective form of snagging. The intent is to hook a fish who doesn't "voluntarily take the hook into his mouth". That's a far cry from a fish who either tries to eat bait or attacks a spoon, plug, fly or other lure for whatever motive. The initiative lies with the fish. How do you regulate an attitude? It seems to me we do it all the time; expecting people to adhere to certain standards of ethical behavior whether such standards are enforcable or not.
