Federal law and the laws of 38 out of the 50 states only require the consent of one party to tape record a conversation. I'm fairly certain that Arizona isn't one of the twelve two-party consent states. Even if it were, the Feds have argued that Federal law applies to anything involving interstate commerce, thus I would argue that Lone Wolf was dealing with a Federal agent, pursuant to a Federal firearms license, involving firearms that were in interstate commerce, and thus Federal law should apply.
If he has the recordings, I don't think there's a problem getting them admitted.
