She talked to them for 20 minutes! Glad she recorded it but WHY? I cannot imagine a reason to ever speak to them. For example, Maryland is one of 11 states that have a two party recording law. It looks like they didn’t know she was recording.
So say they or the state charges her. It would have never occurred had she declined to speak to them.
Warrant?
Lawyer!
5th Amendment.
Phone call.
Nothing else.
