Because being a jerk/jerkette is not against the law
A person can be morally challenged and be a jerk/jerkette in this country and not get into trouble for it. Most likely some judge will slap her on the wrist, claim because she was under the influence that she will get the charge reduced to manslaughter, server 5 years, and then get probation. In the mean time, the family of the guy killed will be upset, but the system doesn't work for the victims, never did never will. Putting her into jail will not bring that guy back, or stop someone from doing it again.
