I have a question, on behalf of my father, about his desire to keep a gun in his company car, even though they prohibit it. I realize that since it is a company owned car he has no right to keep it in there if they don't allow it, and they can search the car at their leisure. However, if he kept said gun in a separate compartment (for instance a privately owned locked box kept in the trunk) would they also have the right to search said box? If he removed the box at the time of the search from their property (the car) would they then have a right to search the box as well?
