It began with the Ruby Ridge Potts/Horriuchi dogs, mommy, and infant shootings at the Weaver place. Since then, it's standard cop MO in stand-offs, and no-knocks. They did it at Waco when they shot the dogs belonging to the sect. One by one, wounding them so they would scream and yelp for as long as possible. They shot the puppies one by one and then the mom dog.
Ironic that the end result for the people was much the same as the dogs. Remember that every time you hear or read one of these dog shooting stories. The next step is closer than you think.
Is the cop trained to immediately start running at that point? Because he oughta.
