From the article: "Police eventually had to use a Taser, a ballistic shield and a catch pole to restrain the dog. I'm willing to bet that the dog dropped dead from sudden cardiac arrest as a result of being zapped by the Taser.
I suspect that the police didn't shoot because the incident occurred indoors in a multifamily residence where the risk of collateral damage was too great.
I wondered about the effects of the taser too. Hopefully they’ll follow up on the story.
