Mine have never attacked either. I think I should take them back. They are obviously defective. I mean the media tells me that they are killing machines and evil.
Many of mine may have killed someone including one AR-15. I don't know or care if they did as they did so while in the hands of the police or military. Since I've owned them, they have all been well behaved. But I'll keep my 1911 handy to shoot one of them if they should get rowdy. ;-)
