According to the Hunter Incident Clearinghouse (http://www.ihea.com/documents/2004_report.pdf) there were 60 instances of folks injured in 2004 by hunters "swinging on targets". Only about 10% of these incidents get reported. None of them ended up in the news.
Well, about a zillion people went to the hospital last year because they felt a tightness in their chest, but Cheney was probably the only one who made the news for that.
