From
"Can We Tape?":
"Twelve states require, under most circumstances, the consent of all parties to a conversation. Those jurisdictions are California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania and Washington. Be aware that you will sometimes hear these referred to inaccurately as “two-party consent” laws. If there are more than two people involved in the conversation, all must consent to the taping.
Regardless of the state, it is almost always illegal to record a conversation to which you are not a party, do not have consent to tape, and could not naturally overhear."
These laws were originally drawn up to deal with telephone conversations but are generally used as the basis for recording of any communications.
Ard, I feel your paranoia but they do have to play by the same rules and it happens all the time. When the police don't play by the same rules, the case gets thrown out of court. There will always be exceptions and each case has variables that can impact the outcome but IMO the system, while not perfect, works pretty well given the alternative. How often do we see egregious acts be tossed out of court on technicalities? Alot!
Not to get too off track...I love my X5!!
