Over 600 permits in the Franklin co and surrounding counties may be invalid. Three have been arrested, one is a certified firearms instructor, who was selling signed certificates to the other two. The two then taught a shorter class than required, and sold a certificate to an undercover officer who took no class at all. The officer sold one to his sister who wasn't there for the class at all. I can't post a link with my phone, it should be on the Columbus (ohio) dispatch site.
