In this situation I'd probably have insisted to the crew that police were ready on arrival to speak to this guy. Panic attacks are a serious matter and this situation could rapidly have developed into something that impacted on the normal operation of an aircraft.
As it is, this jerk has left with the idea in whatever pigswill is taking the place of brains inside his head that behaviour like this does not have consequences. This is WRONG. It should have consequences - serious consequences. It doesn't matter what pathetic excuse for manhood this guy has - he needs a bloody good kick there.
