> If the person on the other line is willing to reveal their account to law enforcement, then wiretap should not be needed. If Facebook posts count as telephony, then this varies by state. One-party consent vs two-party consent. If you dial up Bob and Bob agrees to let the police listen in, that still requires judicial approval in California. (To use as evidence in prosecution, anyways.) On the other hand if they don't fall into the specific legal definition of what's covered by wiretapping, then they fall into the Third Part Doctrine. Which means that what you're saying applies: you gave your information to another party, you're at their whims of whether that data gets revealed. The linked article is making a strong distinction about wiretapping specifically and the protections around it, from which I infer that everyone agrees facebook messages are legally phone calls, for whatever reason.
