Igottafly, time for you to stop posting on this subject on this PUBLIC forum. In PA,where I practice, recording without the consent of the other party is a felony 3 violation of the Wiretap Act, and punishable by up to 7 years in prison and a 15K fine. And there is a FEDERAL wiretap act. I don't practice fed, but can tell you there is a reason there has been so much flap about the government taping conversations w/o a warrant. They can't do it either, at least, they couldn't until some of this anti-terrorism BS. I don't know if DC requires the consent of just one side of convo or both, but federal law will apply in DC, IIRC. You need to stop saying what you, hypothetically (and we all know you have been posting hypothetically, just seeking opinions), have done here. And call yourself a lawyer.
I'm not a DC lawyer (so I can't legally give you advice on DC law) but I am an active practicing criminal defense lawyer.
