Irrational, as usual
I would fear a Boston Dynamics robot a lot less than a real police dog. This robot might look the part but its lacking agility, speed and teeth attached to very powerful jaws. The real dog also has better sensors -- it will follow me by my scent and even a mediocre dog is really, really, good at it.
Robots are fun but they've still got a way to go before they're capable of doing anything other than mechanically following their programming.
