the concept may be more established for ice hockey. but it is present in all sports or possibly in life: we hope there is a referee to punish bad behaviour. but if there isn’t, we have to take things into our own hands.

i am not necessarily talking about violence here. if at your job someone constantly tries to sabotage you, violence may not be the best approach. but some dirty play on your side, might just discourage the behaviour enough. obviously that should only be considered, if theere is no sort of referee to stop the behaviour traditionally.
