Robotic police dog shot, credited with averting bloodshed

In theory, police shouldn't be able to use deadly force to protect the life of a (biological) police dog, but they regularly do, and the courts accept it. The argument given and accepted in court is like this; whilst a dog is not entitled to the same protections as a human, the suspect attacking the dog caused me to fear for my life and that of others.
You could give the same argument about a robot dog.
It's not a robotic "police dog", it's a mobile surveillance and weapons platform. You know these things are going to have guns mounted on them eventually, if they aren't already.
I say we have a RoboDog following around every law enforcement officer to record their interactions with citizens and, if possible, protect both sides from harm.
Reading this article has ruined my suspension of disbelief in The Guardian.
