Open carry brings problems, I'm not against it, myself I would still carry conceled.
We had a case up in NH (where it is OK to carry open) where a person from my state (MASS, that says it all there) saw someone carrying and went running scared, called the police saying there was a mad man running around with a gun and things like that. Well the police came saw what was going on and defused the case it was over but not without a lot of head aches to the legal carrying person.
So again my way of thinking is conceled. Looking at your statements, 1. the bad guy doesn't no you are carrying so you have the upper hand and 2. you don't become the 1st dead or shoot person. You can look at it this way too, if you are still in the mix, so to say, you can maybe help someone else (your wife, kid, friend) or even stop anything from happening.
I thought that the shows on "Best Defense" were very good when they were showing the different ways as to how a shooting "could go" when they did the different ways it could go down like in the store or at the ATM. Very good veiwing and teaching.
As i said these are only my views and my way of thinking, I no there will be millions of other views so don't flame me for my views if they aren't yours, that is one of the reasons I don't answer alot of these style questions, but, I wanted to add my thoughts to this one.
