In terms of the production order for this information, this would be a good example of where you receive many IP addresses and you're trying to identify who they might actually belong to. You're trying to identify whether these IP addresses could potentially belong to the victim or to the person who is claiming to be a victim. At that point, you don't necessarily know, or you haven't confirmed, whether a crime has actually occurred. You have, for example, a conflicting statement from the victim, or the potential victim, and the bank itself. You have the possibility that the crime has actually occurred.
If you have only the possibility, you're not at reasonable grounds to believe yet. You need to have, or it would be nice to have, another tool to be able to write the possibility that this crime has occurred. The information received would allow you to confirm or deny, or at least provide evidence of, the offence.
