A dog described as an American Bulldog or Pit Bull was running loose. The dog got in a fight with another chained dog and menaced people. Police arrived and the dog entered a yard. Instead of blocking the hole in which the dog entered to, you know, confine the dog, police apparently milled around.
When the dog got back out of the hole and charged the officers, he was shot and killed.
