You posted two not three references that came about over a period of 3 years. The third story makes no mention of whether the man was CC or OC. I open carry because it's my right, I also am always aware of my surroundings. I have only had one incident where my weapon needed to be drawn and that was many years ago when I only CC'd. The poor mexican kid with the extremely large wheel gun sure had a surprise that day. Since myself and my wife have been OCing neither of us has had a single incident. So by your standards CC is more dangerous since we have had more trouble with it than OC.
