Was her DUI an felony arrest? It depends on your issuing authority.some States have strict Regulations when it relates to DUI infractions. I do not believe it will be an issue, but She must disclose any, and all information from that charge including an Court Disposition.
Including the paperwork for Completing the School. Seems allot of work just to carry a Stun Gun. Might as well go all the way, and Carry an Handgun. In my opinion. I understand completely that some people just don't feel comfortable carrying an Handgun.
Good luck to you. Let us know on the outcome.have a nice day.
