I am sorry to interrupt but I only have a limited amount of time. If I understand correctly, you are saying that section 19, which amends the Access to Information Act, requires specific businesses to disclose the identity of offenders. I will have to find the actual section but I think you are referring to section 21. This section could also apply to Internet providers. It would be a pleasure to give you the information.
