And you would trust your freedom on her doing what she said? I am sure some SP's really would delete it. How do you figure out who they are? Certainly not through reviews. No-one will know who has been keeping a log and not deleting data until the police come knocing. A little too late to find out?Why can't you tell her to erase all recorded communications after the session?
Again, whether this becomes a concern will depend a lot on how the law is enforced -- but if it is enforced I can't see anyone trusting their future legal security to a 19 to 25 year old SP or her booker.
