Let's be honest - how many times have U got drunk and assaulted someone?
For me it is zero - when I used to get drunk as a kid - well merry - I would be in no state to assault anyone - the 3 & 5 legged pub crawls were bad enough (the things we do for charity

)..
So IMHO blaming alcohol period is wrong. The law has been biased towards using excuses as a reason why the person who did "xyz" was not really meaning to do it and in the clear light of day they are as good a citizen as the rest of us.
I would establish a cost for any and every assault being 1) the cost of police time, 2) if required the cost of any other professional service - Ambulance / Fire Brigade etc.
Before any charges can be heard the parties involved must pay upfront or go to jail until they can - jail being a low security affair in a remote town - i.e. outback.
1 month of jail time = $1000.00 till the debt to society for abusing the public facilities has been paid. If one party can pay (being exceedingly rich) and the other can't then both in till debt cleared.(First cut open to being refined!!)
Then the court case can go ahead with the usual appalling approach to the reality of the outcome on the victims.
The basis here = responsible for your actions regardless.
I do not think absorbing the public facilities free of charge for this use should be at no cost to the abuser(s)...
We have created a very insulated culture once you are on the inside (i.e.an AUSSIE) - to our detriment. (American (US of A)prisons are basically privately run labour camps).
So many other things to do than use alcohol as a prop to assault others...
