Tiny donkey. No threat to anybody.
You don’t know donkeys do you? We used to pasture a large (16H) quarter horse and a miniature donkey together. One day a couple of stray dogs got into the paddock and chased the horse who tore the place up trying to get away. The donkey ran after the dogs and kicked the snot out of them, killing both of them.
There is something profoundly broken in some people. “It was a potential threat”; means you need to find another line of work. Split second decisions are not part of your skill set. The excuse proffered actually proves it.

Some LEOs just don’t have the temperament for that line of work. Based on the initial info, the LEO that killed that donkey is one such officer.
Damn heartbreaking to see the girl crying over the body of that donkey.
The reports states that the police entered the property a bit after midnight while chasing a “suspect”. The owner was not notified. I have had cops come to my house during daylight hours and they asked me of they could come on my property looking for a suspect. They asked me if I had animals on the property and/or dogs. I said “no animals” and gave them permission to go on my property. The police would not wake me up at 12 midnight to ask for permission to enter my property or ask about animals.
So if an animal comes toward the cop in the dark, that could be a giveaway to the suspect as to the cops location and cop could be an easy target if the suspect has a gun. Supposedly cops tried to taze the donkey first.
I feel terribly sad about the sweet little donkey dying. Restitution and more should be made to the owner. But suppose the donkey gave the cops position away and the cop AND donkey were killed by the suspect? Even more sadness, and suppose the suspect got away? Overall, a tragic and terrible sequence of events.
According to the book of the Revelation, there are animals in heaven. I am sure sweet little HeeHaw is there.
No kidding, idiot jack-booted thugs.
