Are you breaking the law when you record encounters with police officers?  Apparently, you are in Maryland.  In Tennessee, however, I would argue that Tennessee Code Annotated sec. 39-13-601(b)(5) applies:

It is lawful under §§ 39-13-601 — 39-13-603 and title 40, chapter 6, part 3 for a person not acting under color of law to intercept a wire, oral, or electronic communication, where the person is a party to the communication or where one of the parties to the communication has given prior consent to the interception, unless the communication is intercepted for the purpose of committing any criminal or tortious act in violation of the constitution or laws of the state of Tennessee.

In any event, it is absurd to say that a police officer on duty in public has some expectation of privacy, where the person he is encountering does not.

Iguess this guy just couldn't get a date.

Three burning legal questions.

Woman Follows Directions, Gets Run Over.  Because there were no sidewalks on the route she followed, she walked on the street, got hit by a car, and is suing Google.  Maybe she should have looked at the street and used some common sense? 

Criminy, I've got a Google Map linked to my web site, too.  Please don't sue us....
