I told this story earlier in the thread and it is anecdotal, but I am in the ATM business and carry open when in high risk areas putting cash in ATMs. I know for a fact that my open carry in those situations has deterred a robbery. A patron of one of the establishment told me that robbery was considered by someone she knew, but never happened because they saw I was carrying.
Other than that, you can't prove a negative. How can you come up with statistics which show what didn't happen? I know this, if I was a burglar and had the option of robbing two houses and in one I knew the homeowner was armed and the other I knew the homeowner was unarmed, I would rob the unarmed household.
I'm not a big proponent of open carry for a variety of reasons, but do believe that there are some advantages in some circumstances where it is appropriate and a deterrent...
OC is useful in many scenarios. Open carry advantages as a deterrent? Thoughts, pro's and con's?
As an easily understood reason? - Why else would many law officers OC if they didn't think it would work to some degree as a deterrent besides the intimidation or scare factor to many people? And, ease of use is easier and faster with OC. If OC didn't work to a large degree or part, they as a group also wouldn't likely OC either? But, many also carry a backup CC as well. So, there's that?
Main con of OC? - Element of surprise is sometimes lost? But, on the other hand, the "other" element of surprise may also be lost with OC and the surprise element is not needed if none is there in the 1st place from either of party's?
