The officer was indicted for murder even though the woman was apparently pointing a handgun towards the window, scared of the noises policeman made in the garden. Much like in Moore's story, the killed woman was not expecting cops to come and cops failed to announce themselves as such.

Never mind UK or Finland, even in Texas it's a murder.
