not sure if I am missing something here.
Police knock on door\ring door bell.
Door opens and a dog comes out, a pit bull ?
at that point, what is proper police procedure ?
It’s up to the cop. If you reasonably feel the dog is about to cause you or someone else physical injury then you can shoot. This dog did not charge, it wagged its tail, and it actually stopped and turned to look at the other officer. There was no imminent threat of physical injury to the officer who discharged.
Happened to my niece and a cop shot the dog in the front leg crippling it. They left the dog and family in agony.
I sure as hell hope you aren’t one of these trigger happy LEOs but you are asking for permission to shoot...
