My question involves criminal law for the state of: California
I need Help. Me and my live-in girlfriend who has a son by me had a confrontation. It all started when I returned from work. She does not work. We had been arguing for the past few days prior. So we decided to break up. Now i am in the living room and she along with my brief case are in the bedroom. But on this day she went into my brief case and found the birth certificate of my son. How I got it i took it out of her file box a few months earlier to make copies of it and i forgot to give it back to her. I come into the bedroom and she ask me how did i get the certificate. She takes the certificate. The copies i made she put them somewhere i could not find. So I grabbed the certificate off the bed. She brases up to me repeatedly trying to snatch it from me. I tell her let me go make copies and i try to leave. she wont let me leave the house. this goes on for about fifteen minutes. Our 2 year old son is crying saying stop. I look at my son and tell her to look what you are doing to our son will you please let me go and make copies of this. She looks at my son and then look at me with a Smirk. All of a sudden she goes into a frenzy. She gets my brief case toss all of its contents around the living room floor. She grabs my pager and cell phone off my belt and throw them across the room. At this point I am still trying to get out of the house but she grabs onto me. I push her back and she grabs a knife off the counter top. She raises it and I lunge towards her grabbing her arm. She is swinging her arm trying to stab me. I get a few cuts on mt bicep. At that point I punch her in the head. She drops the knife and run outside screaming.
I call 911. I have my son with me inside while she is outside screaming for help. The police arrive and take my statement. They take pictures of my arm which is scratched and cut. Then they arrest me. She goes to the hospital complaining of a hickey on her head and dizziness.
I went to jail and got out in the middle of the night. I called the police station and they said she was cited with domestic battery also. but she was not arrested.
My question is since she was the agressor and I was only defending myself how good are my chances of getting this dropped?
