Actually, I'm in the midst of writing a kind, LONG letter to that city/the PD ect.. It also may get me nowhere, but I am making some suggestions in there about how to better handle a situation as this, and talking about the dog in that particular instance.
If anyone else would like to, it would be nice.
I think the petition is more to show support for some kind of action against this happening again, or to at least have the officers enlightened on what they did wrong. You simply cannot say the dog was out of control while it's on a catch pole, it had actually given up it seemed before he shot her. I can say that both my pomeranian mix and my german shepherd would react the same to having a pole attaching to their neck by strangers.
Edit*
I though police were only permitted to kill domestic animals if they are a threat?
