It hasn't been dozens; it's been a few. One thing that's been remarkable about this is how few people have actually spoken up.
I'm not sure it's entirely fair to blame the public service for the problems. I think that in many cases the people are over-tasked and are doing the best that they can. However, where there is wrongdoing, people are much too afraid to go public, and in some cases, the details of the case will give away where they are and what they're talking about—for example, the employment subsidy.
