Exactly. Regardless of others’ opinions on whether or not the dog should have counted as an LEO, he was still firing a gun in the general direction of the officers on the scene, and as far as I’m concerned that’s plenty of cause for the officers to have shot him - how were they to know he was actually intending to shoot the dog, and it didn’t just get in the way, or he missed and shot it instead of the officer he was aiming for, or something like that? In general, pointing, and especially firing, a gun in the direction of an LEO is probably the stupidest thing this guy could’ve done, and basically asking to be shot.
Now this is an interesting scenario. Could it be the cops already had their guns trained on the guy and then sent the dog in so as to give them a reason to shoot? Interesting that the cops went for a head shot instead of center of mass unless they were real close. There very well may be more to this story.
