What few statistics available show that the accident rate has not increased since reaping has become popular, so their is no correlation to ban it other than opinions that it will lead to more accidents. Using that same logic, they should ban all elevated hunting options because someone might fall.
That's an apples to oranges comparison for turkeys and deer. The only comparison would be in states like VA, that allow rifles for turkey hunting. Would I use a fan there - no. Will I use it in SD and NE in a few weeks on the prairie, absolutely. I'm not a fan of decoys and don't actually use them, but up there, it works and you have more odds of seeing game than people, so I bought one for the trip.
