Assuming facts not in evidence. It’s equally possible two thugs could target someone openly carrying a gun to steal it. They would be alerted and would approach more cautiously to get the drop on him.
I agree! Depending upon the time and place it would be easier to distract the carrier while the other make his attack. I have 35 years experience in federal law enforcement. I have never felt secure open carrying even in uniform. CCW should provide the element of surprise if you are aware of the situation and the degree of danger. If you happened to be in bank or business which was being held up- open carrying who do you think is more likely to be targeted?
Concealed carry just might provide more time to evaluate the situation and the element of surprise to lessen that innocent bystanders get injured or killed.
