The linked article is another great example of the low standard of American journalism. It is lacking in reporting the important facts.
How did the invaders gain entrance?
Who were the occupants and how many were in the apartment which was invaded?
What was the weapon used to defend? ".22-caliber rifle" is the inadequate description? It could be a rimfire or any of a number of 22 caliber center fire cartridges.
How or why is shooting the invader in the back justified in this case?
Basic newspaper journalism should objectively report the facts and answer: who, what, when, where and why.

they create for themselves in the course of time a legal system that authorizes it and a moral code that justifies it." Frederic Bastiat
