Murder. Attempted murder. Voluntary and involuntary manslaughter. Vehicular manslaughter. These are the cases with the longest sentences and the least room for error — where the prosecution's theory has to be attacked at every joint: the forensics, the timeline, the identification, the alleged motive, and the witnesses who have their own reasons for saying what they say. Self-defense, imperfect self-defense, and heat of passion are not afterthoughts in these cases. They are frequently the entire case.
