Alan, I must gently disagree with you. In many states, not all, it is
illegal to intentionally record another person, regardless of whether it is
being done from your apartment or wherever. It is only legal if the
other person is made aware of the recording process. This is not the law
everywhere, but it is the law in over half the states. Sadly, what seems
to make sense and what the law says are not always congruent.
