Q: If he had been talking with his lawyer, would the conversation have been recorded?
A: You would have to ask the jailer that.

A: You are correct.
Q: I was equating it to talking with an officer before Miranda. If you confess before being officially questioned, your confession counts. I know that's too simplistic, but it's a basic rule I believe.
A: You are correct. If the officer says to the waitress, "One doughnut, please. I'm on a diet" and the waitress says, "Before I came to work this morning, I killed my husband and here's how I did it." And then confesses. That's a good confession.
