How to handle a problem
Knoxville TN: a police officer, mistakenly thinking that if you have a CCW permit you MUST carry concealed, grabs, frisks, and threatens to arrest a permittee who was carrying openly.
The Chief of Police sends an apology, and a promise that officers will be given additional training in firearm laws. Although not in the story, the officer involved probably got some private criticism, if not a chewing out. That's how you handle things.
