-or- how about heavy falling snow?

-or- how about very windy conditions?

Lately I haven't been seeing the super ethics police twirling their nightsticks but what would they say about the questions posed? Obviously, rain can quickly wash away a blood trail while falling snow could cover it. At the same time, high winds could make a bow arm unsteady and on top of that throw an "on course" arrow "off course." If a less than perfect shot is less than ethical, wouldn't less than perfect conditions be the same thing?
