You said, and I quote "Your argument that if a "victim defends herself or himself by hitting another person," while I understand what you are saying, still doesn't fall into the legal definition of self defense. "
Therefore, by your definition ... a rape victim must be arrested for fighting back, a mugging victim must arrested for fighting off their attacker, etc.
It's always one person's word against the other.
So, by definition, everytime any physical contact takes place between two parties, the police MUST arrest both parties and let a judge or jury sort it out.
I clearly disagree.
