It occurred to me when Comey was testifying yesterday to ask: "You were the FBI Director. You had access to all sorts of gadgets. After your first uncomfortable meeting with Trump, why didn't you wear a wire in person and record your phone conversations with him?"

That question in turn raised a legal question. Would it be legal?

Apparently yes. Washington, D.C. is a one-party consent jurisdiction, meaning that it is legal for a person to record his own conversation with someone else, even without the other person's consent.

Trump's modus operandi when facing unpleasant accounts of his behavior is to deny it, to attack the character(s) of the source(s), to completely mischaracterize the account, to claim that his own behavior as described was not a big deal (e.g., "locker-room talk&quot , and to just claim vindication in general terms.

Wearing a wire won't protect against all of these moves, but it will protect against the first two.
