Animal Legal Defense Fund’s is suing the City of Seattle for making the lives of several elephants at Woodland Park Zoo not worth living.

The Seattle City Council, Woodland Park Zoo management, and the Zoo’s Board of Directors have been made aware of the inhumane practices for the last five years and continue not to improve the situation. The elephants spend 16 - 17 hours a day for 7 months of the year in a tiny barn stall the human equivalent of about a 4 foot square closet. Outdoors they have less than 1 acre.
Elephants, which are recognized by the most intelligent animal, humans, as intelligent creatures (not only do they have the ability to recognize themselves in mirrors but they can also play football), require lots and lots of room. ALDF believes that the "elephants need to go to the 2,700 acre Elephant Sanctuary."
That's happening in Seattle; this just happened in Vancouver:
[A] provincial court judge had the unpleasant task recently of having to deem a family pet dangerous after it bit three people last year.

One of the bites caused severe injuries.

Dangerous dogs have to be put down, according to Vancouver's animal control bylaw. As a result, the eight-month-old puppy, a Korean breed of hunting dog called a Jindo, had to be euthanized last Friday, after the 30-day appeal period expired.

The owners of the violent animal (an animal that lived with humans and had a taste for human blood) did everything they possibly could to keep it in the business of biting people. Their insanely singular dedication to the dog even impressed the judge:

Judge Paul Meyers tried to offer the Korean owners comfort when he told them they had done everything humanly possible to save their dog named Scott.

"If it is of any help, I can tell you that I have never in my 10 years as a judge, seen anyone fight so hard, so long, and put so much effort and money into saving their dog than the Shin family has," the judge told the owners, Sue Kang and Young Mi Shin

"If anyone were to ever criticize you for not doing beyond what was humanly possible to keep Scott alive, they would not have heard these words of mine.

"I have never seen anyone, Jindo owner or otherwise, who has done more, or a family that has done more, in cost, time, and effort to try to save their beloved pet."

How is it possible to live in a city with a dog that is in the habit of biting people? Why is it hard for the owners to see that this is a serious problem? Why all this effort against the rule of reason? Why?
