As HC has already informed you. You are completely offbase on this.

You are probably confusing the necessity of a warrant for a third party, usually LE, to record phone conversations.

Let this also be a warning to anyone hoping for legal advice from a bunch of anonymous posters on a fuck board, the advice you get here is usually worth every penny that you pay for it. Even the"legal board" on TER has more incorrect and potentially harmful advice given there than good. Again, please take the advice you get on a fuck board, or any other internet board for that matter, with a HUGE grain of salt.
