Group/party hunting has many different connotations. In Wisconsin at one time, you had party tags for antlerless deer, but group hunting was illegal......altho large deer drives for deer was and still is....legal.
For many folks, when they hear the word "group hunt", the first thing that pops into their head is a "drive" hunt, where a group of drivers forces game to another group called standers. Here, "group hunt" means that any number of people can join together and contribute to the total legal bag limit of the group. Used to be, while a group of people could drive deer to another group of standers, only the person that had a valid tag could shoot and only the person deemed to have killed the animal could legally tag it. With the old "party tag" system, it took a group of people to apply for a single tag, and anyone in that group could shoot the animal, but only if and when the tag itself was in their possession.
Cornfused yet?
That said, I'm bettin' the episode in Iowa was with dogs running 'yotes. It was not a case of misidentification, but probably a shot that went beyond it's intended target, either directly or because of ricochet.
Around here houndsmen runnin' yotes have gotten a bad rap, in a case of one or two bad apples spoils the whole crate. Wisconsin Private land is basically small parcels of under 200 acres. Getting permission to hunt private land is difficult at best because of known problems with the doggers. So many times they hunt the roads, while allowing their dogs to run on property they do not have permission on. Many times those unattended dogs get into things and places they shouldn't be. Sometimes they get hung-up and the owners trespass to go get them. Sometimes it's easier to cut a fence and use a ATV then to walk in. Sometimes to avoid being seen on trail cams, trail cams are stolen or broken. It goes on and on. Sometimes regular folks driving on public roads see doggers illegally shooting from and across the roads they are waiting at, and feel they are at risk....and rightfully so. Thus a few tend to make the rest of the good, responsible law-abiding houndsmen look bad also.
Group hunting and deer drives, when done properly, have no more inherent risks that any other form of hunting. What puts folks at risk is the compresion of folks and game into a small area. Thus one needs to be even more aware of and practice the rules of gun safety even harder. Again, the use of Blaze orange has greatly reduced shooting incidents during the gun season as people are just more visible. Put folks in camo and that advantage goes away.
Banning certain types of hunting for all because a few make tragic mistakes is
not going to change the irresponsible. Like those folks around here that trespass and shoot from the roads in an attempt to get around the rules, those folks will still do stupid things like shoot at each other. IMHO, maybe a law where groups of more than three need to wear Blaze orange would work better than a complete ban. I dunno. I tend to stay away from most drives and group hunts anymore because my type of hunting demands it. To others tho, in certain scenarios, deer drives are the only feasible method to get deer to move during daylight hours. It just has to be done safely.
