I know the NYPD I worked with. Always had to keep their attack Dogs out of reach of the public. Don't know if it was policy or just being smart.
Either behind a counter or some type of barrier where no one could reach it. They were very aggressive, the way they should be. The sniffing Dogs on the other hand were always out and about with the public.
There are also signs all over Airports and Train stations telling the public not to approach or pet these Dogs at any time. Yet I saw people do it. Even people telling their kids it was OK to Pet the Cute Dog.
