Considering the police officer is on duty and inside the precinct - which is aimed at serving the public, I wouldn't consider this "playing music to yourself".

Otherwise, every employee in bars and restaurants could "play music to themselves", without paying anything and without infringing copyrights ?

That he is on duty is irrelevant. If he's playing music for himself - even one other person, it's not a public performance.

The arguments being made here are infantile, and embarrassing.

Because people 'hate cops' (shameful), they use magical thinking to twist even common sense upside down.

The person making a video public is the person making something public, not the cop.
