Yes.
And the reason behind that "yes" answer is simply because I don't know if that person is carrying legally; I don't know whether they are in the store to fire that gun at one or more people, or not.
That would depend on where I am, if I actually SEE a badge, etc. etc.
You can play the "what if" game with all kinds of scenarios, but when it comes right down to it, I will do as my initial post stated.
You are giving me the impression that you believe I am against people legally carrying concealed weapons. Well, I am not. If people feel the need to carry for personal protection, safety, whatever reason - if they are carrying legally, that is their right. And in this day and age, with the increase in gun violence, I also have the right to do what I feel I must do to keep safe and that means to say something when I see something. My suggestion would be that if someone is carrying a legally concealed weapon and doesn't want to be reported, they should make sure it stays concealed.
Based on my own personal observations, I believe Jesus Christ seems to be staying out of gun control issues.
