For my story, I want the MC to be able to record a phone conversation with the intention of using it as evidence. Now it will probably be best if I set it in a country (probably the U.S. or Canada), that is a second party nation. I read that a lot of states are second party, where you can record a conversation if you are a part of it. However, in my case the MC is using someone else's phone ID and impersonating that person to speak to the villain. The villain thinks he is calling a contact of his, but it's actually the MC, impersonating the contact. Would the MC be able to hit the record button on the cellphone and it can be used as evidence if he is a part of the conversation, but the villain thinks he is talking to a different person? Or does the second party law mean you can record any conversation no matter who you trick the person into thinking you are, since you are still a part of it? Also the MC would have to make his caller ID's appear to be the contact's, so the villain can be fooled. Is he has to do that, to trick a person into giving up evidence, will the evidence be admissible? Also, if the villain has to hang up, but then call back his contact later, let's say he hits redial in his phone. Since the MC has appeared to make his phone number be the contact's one, the villain's phone would still dial the real contact, and not call the MC back, right?
