Zackly! Dog wasn’t leashed to begin with.
The Dog’s protection is on the owner. That leash is protection for the dog as well as others. There are suitable places to allow dogs to be off a leash.
I love dogs as much as anyone but if a strange one makes a move toward me I’ll Rick Perry it without hesitation.
So, no, I don’t blame the guards.
(A cop killing a dog in its own yard is another matter.)
