KenK - It is illegal for anyone in Michigan to videotape another person in a place where this other person should reasonably expect privacy unless ALL people involved are aware they are being videotaped. It is a felony punishable by up to 2 years in state prison or $2000 or both. Audio-taping is not illegal if at least one person knows they are being audio-taped and the person audio-taping is a participant in the conversation - "eavesdropping" (where the audio-taper is not a participant) IS, however, illegal.
