You make a good point. I have a friend in local law enforcement and it’s common for the 911 operators to get calls from citizens because they’re in a restaurant or something and they see someones gun. The 911 operators just tell them that CC is legal in Missouri and politely tell them to chill.
We had an episode here in San Diego North County where someone called in a report of a rifle on Campus, THe place was locked down SWAT called from all over roads closed, you name it. Turned out it was a professor carrying an umbrella.
