Gun Control & RKBA

donP: .... Been over a year, still waiting for that first open carry shoot out everyone predicted

You obviously do not understand what the word 'everyone' means. Pls consult one of our fine online dictionaries before using it again.
Can you post an example of anyone contending what you described in your post? so we can read it in context? or are you fabricating just another imaginary gun scenario like you did with those knife owners being wrongly depicted as killers by us gun control advocates (note: not one gca did what he alleged).

911 Operator Allegedly Cited Open-Carry Law and Refused to Send Cops Before Colorado

Moments before a man went on a shooting rampage in Colorado over the weekend, his neighbor reportedly called 911 to report that he appeared to be distressed and was brandishing an AR-15 assault rifle. But instead of sending the cops, the dispatcher allegedly told the caller that it's perfectly legal under state law to openly carry firearms in public.
The man, identified as 33-year-old Noah Harpham, gunned down two people before police in Colorado Springs arrived on the scene. Harpham claimed one other victim before he was killed in a shootout with police. Authorities are not releasing the tape of the 911 call placed by Harpham's neighbor Naomi Bettis, and it's unclear whether the dispatcher ignored a reasonable report of suspicious behavior.
Bettis told the Washington Post that she called 911 on Saturday morning to report her neighbor, who was standing in his yard holding a rifle.
"I couldn't tell if it was real or not, it being Halloween day, you know," Bettis said. "But that's what I told her, and all of a sudden she started saying something about— I don't remember what they call it — open arms… and she said, you know, we have that law here. And it just kind of blew me away, like she didn't believe me or something."

dispatcher was apparently referencing Colorado's lax open-carry laws, which allow citizens to carry assault rifles and other firearms in public without a permit. In other words, Harpham's behavior was legal right up until the moment he opened fire on random people on the street.
