That hunter/poacher/pyscho that killed those other 5 hunters, and wounding 3 others was an Oriental. Great, there'a already not too many Orientals hunting....now there will be less. Every other hunter's going to look at an Oreintal as a potential killer.

I don't know what happened there....maybe he's a psycho...or maybe racial slurs were thrown at him.....and he just freaked out. Not that I'm condoning his actions.

Back to the original question....best way is to let the landowner post signs and/or tell those poachers to leave the area.
