Gee, Chief,
Anybody could be driving a car without a driver's licence and/or at least the minimally mandated level of insurance. Why aren't cops stopping automobiles to make sure the drivers are properly complying with the law - especially since cars kill more people than guns. Or women? Last I checked all of them carry the equipment to commit prostitution.
Stopping the car that is being driven erratically, or significantly over or under the speed limit may be an appropriate response. Checking on the woman who, especially during the hours of darkness, leans into the passenger window and talks with the drivers of lots of different cars may be an appropriate response. Just like stopping the Open Carrier who keeps finger-*expletive*king his handgun may be appropriate.
But if you are going to be stopping and checking people who are Open Carrying because they are Open Carrying, you had better start with those who are most frequently seen Open Carrying. Without doing so how will you know they are real cops who can Open Carry without a license/permit?
I know that it is considered bad form to pick on the mentally/emotionally challenged, but it is just so darned much fun.
stay safe.
