Passing a law to address this problem, just gives cover and legitimacy for the next LEO that shoots a dog.
I would dare propose to you that a solution is already being implemented and no further action is required. The uproar created in that local community is being noticed by all in that community. No officer wants to noticed, and they are all talking about it. They know if they do it, they are next. There is NO COVER or MEANS to justify this action, until you give them the protocol through another law! THINK, PEOPLE, THINK!
When in hole, keep digging. I’m not reading your long post so don’t look for answers :)
