So I'd this realistic you commit manslaughter, killing innocent guy who tried to saved your sister and done nothing wrong and because you were emotional you serve only 2 years for killing this innocent guy?

I mean if she killed the father who kidnapped her and drugged hey for 2 months I could see it as being emotional and maybe appropriate for such manslaughter, but doesn't seem very realistic for killing the innocent boy, but I'm not familiar with US law.
