I would assume that the host/Observer only found out about the professional sound system after the party! Not exactly something a shady guest would inform the host about up front. I am also puzzled why the guest isn't being pursued for the damages, though. Surely AirBnB can pull up the guest's reservation information and pass it to the authorities? This would seem a fair response given that the police were called so many times.
