Have you watched the video?
There's only a few seconds between the "close the door" request and when the dog bounds out.
There just wasn't enough time for the right things to happen.
Whaaa? Why did the cop have a shotgun in his hands? Right things to happen? Whaaa?
I once called the cops because of a rabid racoon wandering in circles in my backyard.
Did the two cops who showed up take it out with their batons? Nah... to easy.
They followed it thru three yards and spent half a day on this big case!
If I were the family, I would sue that town back to the stoneages.
