I WHOLEHEARTEDLY disagree! "Given the current hysteria," I believe MORE people should carry openly. We need to send a message to those who wish to do us harm: "We will NOT die willingly. You better be 'well-regulated' or you will be the first to die."
This strategy should be adopted in any state that allows open carry. Rifles slung on shoulders, pistols in holsters, shotguns and bandoleers, have them at the ready and go about your business. If every gun owner in the country carry openly during the commission of all of their business, violent crime in the public arena would PLUMMET! No criminal would be stupid enough to attempt seizure of that weapon at the risk of being killed themselves. It's all a canard.
Remember, when it comes to violent crime, there are 6 stages:
1) Intent
2) Interview
3) Positioning
4) Attack
5) Reaction
As a responsible gun owner, you should be intimately attuned to your environment and surroundings, and as such, you should be aware of anyone angling to do you harm, take your weapon, or commit a crime.
Judging by a lot of the people I see at the range, hunting, gun shows, shops and CC classes, there are a lot of gun owners/carriers, that simply are not responsible.
