If the police were to ask one of them in a situation where, say, a young woman had provided an intimate image to someone consensually, but then became concerned, because of other text messages between the two, that the person who had the image might then post it somewhere on the Internet...and she doesn't know who that person is or where they are.
Let's say Rogers is her Internet service provider and you are acting for Rogers. If the police ask Rogers to give up the information that would allow them to find out the identity of the person who has that image, what would you advise your client to do?
