Several children trespassed into a neighbor's yard (unknown whether this was front/back or if fence surrounded property, assuming not w/ the chaining) and began throwing rocks and other objects at a chained dog. At some point, one of the children got close enough to the dog for her to scratch and/or bite the child once on the stomach.
Police were called.
Police entered the property and approached the dog who acted aggressively. The police were able to catch-pole the dog. They then tasered the dog. Finally, even though she was secured on a chain and with a catch pole, officers shot her three time, killing her.
The dog's owner is suing. Meanwhile, the chief of police argues that shooting a chained, tasered dog was the only option available to the officers.
