From Koos Hassing:
"Some dogs fight very hard with the helper due to nervousness and some due to dominance. For some judges it is very hard to see the difference, because they have not enough knowledge to see it. In the protection phase, how many judges can see that the dog is confronting the helper or begging for the sleeve? And than dogs get high points, use for breeding and produce worse dogs. On this way of judging they kill the working abilities."

Aaargh, even the judges don't see it sometimes. How is a lesser skilled person to know?
