Culling is never a pretty sight. Given the chance the guys would have probably used a high powered rifle, and the scene would have been looked upon as culling. Put a guy in camo walking around with a bow, stir in a dose of slow dying elk, and sprinkle with a good amount of ignorant passer by and it's a recipe for "Anti-Hunter Surprise"! The situation sucked for sure.
Around here you can get a permit to kill deer out of season if you can prove substantial crop loss, but I have never heard of corraling deer and letting hunters have at it. One thing for sure, it will be used against us.
