Or, ya know, a jury goes rogue.

A homicide may be considered justified if it is done to prevent a very serious crime, such as rape, armed robbery, manslaughter or murder.

Were any of these in play in this situation?

Further

A homicide performed out of vengeance, or retribution for action in the past, or in pursuit of a "fleeing felon" (except under specific circumstances) would not be considered justifiable.
