Two comments......
(1) I am all for defending your domicle, and would gladly would blow away a perp if they tried to rob me. OTOH, that many shots fired nilly willy in an apartment complex is pretty damned irresponsible.
(2) Article reported one perp dead in a hall. Pretty strange that after this camera survey of the entire hall, (where shots were fired), that there is no evidence of blood.
This all doen't really add up.
