Exactly. Here's an example of the type of law you are talking about. I live in a all party consent state, so if you want to record a conversation with me, legally, you need to have my consent. Some states are one party consent states. You can record any conversation you want. Across state lines, federal law requires only consent of one of the parties. But that doesn't resolve anything. Courts in different states handle cross-border complaints differently, some enforce their local all party standard, others demure to the other jurisdiction's one party laws.
