it is their nature to protect their property from unknown invaders, that’s why we have them.

I think you may have swerved into the root of the cop dog shooting epidemic.

"Protect our property from invaders" - the government and its agents don't like this concept. For one thing, in their worldview, you should not be claiming anything as "your property".
Secondly, it is inherent in the "progressive" worldview that you have no right to defend yourself from the government or its agents - you are to SUBMIT.

Now, I think we're getting closer to the "why" of all the dog shootings.

You may be right about me; I never was to good at that whole “SUBMIT” thing, other than to GOD.
I find that the older I get the less submission I have in my heart or soul, so be it.
If you look at my tag line you should get a pretty good idea of what I would like to do with Prog/Lib/Dems.
