Lost -
I understand your anger at your situation. No one should falsely charge another with a crime they haven't committed. I'm sorry that you have had to go through this if you were not at fault.
I have to take exception to alot of what you are proposing. First of all, most domestic abuse is perpetrated by men. Women are no more devious than men - especially alcoholics. I do believe that the cops are most likely to believe that the man is at fault upon arrival on the scene. When a cop recognizes that one party is drunk and the other sober they most likely will look to the drunk.
Some of what you are proposing would leave battered and/or terrified women alone in a very dangerous situation. My ex was drunk, tried to lie to the cops but couldn't keep his stories straight. I was sober and damn scared. Cops can tell when someone is scared.
I agree that the man shouldn't automatically be blamed but what you are suggesting would rob the weaker sex (physically) of alot of protection.
