I suspected that although it runs counter to the law that existed when I patrolled. In the 1980s it was forbidden for officers to maintain a list of firearms owners.But when I noted the number of traffic stops monitored in recent years where the dispatcher advised “a caution indicator” it was likely the rules had been bent,circumvented,or changed.
An officer with any brains will know that ANYONE could be armed and that you should be ready to respond IF NEEDED but not go around with a “hair-trigger” mentality.
It would make more sense to advise the officer making the stop that the car owner has a CCW permit and, thus, NO caution is necessary.
Statistically, CCW permit holders are more law abiding than any other group, including Roman Catholic nuns and police officers themselves. (Both stats are absolutely true.)
