I agree, interesting article.
I admit, I don't understand the need for an officer to disarm an otherwise lawful citizen during a traffic stop (see comments in article). The average citizen, or officer of the law, would never know I'm carrying if they met me out in a restaurant or other social setting. But all of a sudden I become a threat when they pull me over and I tell them I'm lawfully carrying.
For the record, I have never been disarmed by a police officer, but the idea of it happening seems extremely insulting.
I understand that police officer members of this forum may not operate this way, but I would be interested in gaining some insight into why some do.
