I think these “botched” executions are on purpose. These are activists.
We had to put down humanely an elderly roping horse we all liked a lot. He was like one of the family.
He weighed about 1000 pounds. The doc said to hold him still but, don’t let him fall on you. He was dead before he hit the ground. 10 seconds from the shot to totally dead.
Next time, Tennessee should just call a vet.
