Humans can be angelic or demonic. Evidently this lady has opted for the second of the two options. How very unfortunate.
The police should take custody of the dog and return it to it's long term owner.
She -volunteers- for the cop's K9 program.
They're not gonna take the old man's side when he can offer them nothing that benefits them.
I hope that it's just your sadness at the situation that's making you say that, and that you really don't mean it...
The police enforce the law. It appears that this evil, vile creature who's keeping the dog has done nothing that violates the law.
Do you really want to police to sieze the property of one person and give it to another, when the law has not been broken?
