When customers order something and expect it to be delivered to their doorstep they are inviting us on their property, I guess it does not occur to most of them "hey, my dogs are out. How is the delivery person going to get to the door?" They should be thinking ahead. With todays technology they should know the exact day that delivery will take place and take measures to insure that the dogs are secured for when the delivery occurs.
But this is the real world. From the Video that the OP posted and watching the dogs interact with the owners they appear to be docile and friendly. However, as stated before, dogs can become entirely different creatures when the owners are not present. I can see how 2 large dogs could terrorize the delivery man. And I could see why he felt the need to defend himself.
It also occurs to me that these people appear to be well off... large immaculate house. Surely they have surveillance equipment installed. Every body seems to these days. Where is the video from them backing up their claim that the driver attacked the dogs? Maybe because it actually incriminates their dogs? Just a thought.
They would rather feed on the public outcry for this driver's job and be the poor picked on victim rather than take responsibility for the actions of their animals.
Shame on UPS for even responding to this situation the way the did. They should be on the driver's side and defending his actions to protect himself from aggressive animals.
I will do what ever it takes to defend myself in a situation like this even if it comes to lethal force. It is the responsibility of the property owner to insure MY safety when they invite me onto their property by ordering something.
