That is wrong on so many levels..My wife doesn't like shotguns but knowing that there is something out there that will cause non lethal results that she could do, intrigued her; being so she gave me permission to get a shotgun.
I do have professional training and I carry everyday. I am trying to get my wife use to having a gun in the house and using a gun when needed. She ,at this point, is not comfortable with guns and and I am trying to work with her on that. As far as getting permission I feel out of respect for my wife it is proper to ask before doing so.Terrible idea, and I'm not just talking about asking permission from a spouse. Firing a less lethal round at someone is still seen as firing a weapon at someone in the eyes of the law. You do not have the training to deploy such a device effectively and chances are you won't have a lethal option as a backup.
Seek professional training for both of you.
