LMPD recruits learn value of community service

Its not eavesdropping if the person recording u is a party to the conversation or the feds are investigating you and have a warrant for a wire tap.

If you put a sign on the shield and on the dash saying all conversations in a police car are subject to recording, then it's not done without their knowledge and it's bugging. Some private companies do that on elevators. They could do whatever they want as long as they warn you.
