There is a breach of etiquette that happens in hunting sometimes where one hunter "scopes" another. He sees a man at a distance and uses his rifle scope to see who it is. In doing this he points his rifle right at the other man. This is not only dangerous but may make the other man think that he is about to be fired upon. I know of one instance where this caused a fight when a farmer was scoped by a neighbor. He punched the man and took his rifle away and to my knowledge still has it. Anyway, using a weapon mounted light as a flashlight is in effect no different than "scoping" when pointing it at another person.
