Depends on the weapon and on the holster and on the clothes. But even if the gun is concealable in principle, why to do so if you can carry it openly, and clothes over the gun will cost you a couple seconds if you have to draw it? Police has to deal with very nasty people. What if there is a fugitive dining at the restaurant?
If their badge is exposed they can carry openly, on duty, off duty or plain clothes. thats the way it was with my department.
These were detectives not uniformed police officers. I have never seen a detective carry their weapon openly. Only one detective in this group had the weapon showing — and it was a she who probably wanted to show her macho. None of the other detectives had their weapons showing.
This Dennys is two blocks from the police station. Surely the police chief has a policy that covers display of weapons by non-uniformed officers aka detectives when in public establishments.
The fact that the police chief here referred to the badges on the belt or around the neck as some kind of justification for displaying their weapons shows that he’s trying to stretch the meaning of “uniformed officer” to cover plain clothes detectives — but it won’t work.
Badges on belts that cannot be seen or hanging around the neck that can be tucked into the shirt don’t make you a uniformed officer.
