Accidentally kill a police dog and see what happens to you.
I worked with a woman who was the daughter of a newly retired canine unit deputy. She said the officers build a much stronger rapport with the dogs than people elsewhere and the dogs are incredibly loyal.
She said years after it happened her father would start to cry when he told of a black criminal in the City of Detroit who, when being chased on foot, cruelly stabbed a K-9 unit dog he grabbed, smiling and laughing as he deliberately hurt and then killed him in front of the approaching deputies.
