Y'all are missing the point. Of course, a cop can pull anyone over for no reason, I am not disputing that. It seems to me that if the officer is just fishing, and does not actually have a reasonable belief that it is necessary to disarm a licensee, he is breaking the law. I can see some valid reasons to disarm, like a lone cop with no backup. Or if the vehicle matched the description of an evil-doer, but then there would be a full, guns-drawn stop. Neither of these was the case.
GC 9411.207. AUTHORITY OF PEACE OFFICER TO DISARM.
(a) A peace officer who is acting in the lawful discharge of the
officers official duties may disarm a license holder at any time the
officer reasonably believes it is necessary for the protection of the
license holder, officer, or another individual.
