Does anyone know if it is legal to leave a weapon secured in a lock box in your vehile when going into a federal building? My wife who has only had her CWP a few months has started a new job with the federal court system. She knows weapons are not allowed in the building, the walk through a metal dector, but is uneasy about asking about the parking lot. (unwanted attention on new employee.) So for now she leaves it at home.
