The DUmmy is trying to make the story into 'killer cop (on the job) shoots innocent victim, and would have gotten away with murder, if not for DU'.
Not even close.
The corrections officer (retired NYPD) got into a fight with the DUmmy's cousin and the cousin's son, on the way home from work. The shooter took a beating, and he shot both men with a .25. The shooter fled the scene, but turned himself in at a nearby State Police barracks after ditching the pistol.
The shootings were not in the line of duty, nor were his current employment status or his former employment a factor.
