Why not get her the permit even if it's for a reason you don't think is valid? It gets one more law-abiding citizen on the "books" as supporting the 2nd and shows Illinois and other places that CCW are wanted and needed....Then SHE can carry if the need/want ever arises. It also makes it so she doesn't accidentally have possession of a weapon in a manner that might get her into trouble....IE you leave a weapon in the car/truck under the seat and she gets pulled over.. etc...
My wife originally didn't think she would never have use for a CCW but I put her thru the course and now she carries honestly about 40-50% of the time...
