Questioning Public safety laws is in itself unethical.
In MN Firearms safety, Ethics are now taught by the conservation officer.
There are too many personal Codes that people live by and feel anyone not walking by that code to be unethical.
One that gets me all the time is in the training films the ethical hunter always looks the part. Always dressed in the latest field dress Bass Pro and cabelas sells and the slob hunter, (read; road hunter, shooting ducks on the water, shooting onto private land and such are dressed like labors/farm boys!
