Basic ethics should be taught in class. Like what??
Like not shooting 100 pheasants for fun and leave them lay.
Not to use a BB gun when hunting deer.
Not to drive around the city with 4 dead bloody deer on the hood of your car.
Not to leave a gutpile in the middle of the road.
These are basically simple ethics I think everyone can agree on, that will help to not give hunters a bad image from the general public. Most are common sense, but there are plenty of people out there that also lack that.
