There is no logical reason for him to shoot the dog before giving her opportunity to put the dog in another room.
Since he did so, his version of the story has less credence than hers.
How is it that her mailman, utility repairmen, meter readers and the like all managed to perform their duties without shooting her dog, hmm?
I have no details on what occurred. I know only what the woman involved said. I simply don’t know what happened. As to your last sentence, it has nothing to do with this. I have not said the cops actions were correct. I have said that we don’t know what happened. That is all. Unless you have access to more info that’s what I have to go with.
