Good cops getting killed in the line of duty has NOTHING to do with THIS story. Because cops get killed in the line of duty, that makes it ok for other cops to kill pet dogs in their own yard?
This is abuse of power and evidence of an unwarranted predisposition to use their firearm.
If the cop was not a cop but a civilian with a CC permit doing this, he would be in deep S. He needs to be a civilian again and without a permit.
